In the discipline of international relations there are contending general theories or theoretical perspectives. Realism, also known as political realism, is a view of international politics that stresses its competitive and conflictual side. It is usually contrasted with idealism or liberalism, which tends to emphasize cooperation. Realists consider the principal actors in the international arena to be states, which are concerned with their own security, act in pursuit of their own national interests, and struggle for power. The negative side of the realists' emphasis on power and self-interest is often their skepticism regarding the relevance of ethical norms to relations among states. National politics is the realm of authority and law, whereas international politics, they sometimes claim, is a sphere without justice, characterized by active or potential conflict among states.
Not all realists, however, deny the presence of ethics in international relations. The distinction should be drawn between classical realism—represented by such twentieth-century theorists as Reinhold Niebuhr and Hans Morgenthau—and radical or extreme realism. While classical realism emphasizes the concept of national interest, it is not the Machiavellian doctrine “that anything is justified by reason of state” (Bull 1995, 189). Nor does it involve the glorification of war or conflict. The classical realists do not reject the possibility of moral judgment in international politics. Rather, they are critical of moralism—abstract moral discourse that does not take into account political realities. They assign supreme value to successful political action based on prudence: the ability to judge the rightness of a given action from among possible alternatives on the basis of its likely political consequences.
Realism encompasses a variety of approaches and claims a long theoretical tradition. Among its founding fathers, Thucydides, Machiavelli and Hobbes are the names most usually mentioned. Twentieth-century classical realism has today been largely replaced by neorealism, which is an attempt to construct a more scientific approach to the study of international relations. Both classical realism and neorealism have been subjected to criticism from IR theorists representing liberal, critical, and post-modern perspectives.

1. The Roots of the Realist Tradition
1.1 Thucydides and the Importance of Power
Like other classical political theorists, Thucydides (460–411 B.C.E.) saw politics as involving moral questions. Most importantly, he asks whether relations among states to which power is crucial can also be guided by the norms of justice. His History of the Peloponnesian War is in fact neither a work of political philosophy nor a sustained theory of international relations. Much of this work, which presents a partial account of the armed conflict between Athens and Sparta that took place from 431 to 404 B.C.E., consists of paired speeches by personages who argue opposing sides of an issue. Nevertheless, if the History is described as the only acknowledged classical text in international relations, and if it inspires theorists from Hobbes to contemporary international relations scholars, this is because it is more than a chronicle of events, and a theoretical position can be extrapolated from it. Realism is expressed in the very first speech of the Athenians recorded in the History—a speech given at the debate that took place in Sparta just before the war. Moreover, a realist perspective is implied in the way Thucydides explains the cause of the Peloponnesian War, and also in the famous “Melian Dialogue,” in the statements made by the Athenian envoys.
1.1.1 General Features of Realism in International Relations
International relations realists emphasize the constraints imposed on politics by the nature of human beings, whom they consider egoistic, and by the absence of international government. Together these factors contribute to a conflict-based paradigm of international relations, in which the key actors are states, in which power and security become the main issues, and in which there is little place for morality. The set of premises concerning state actors, egoism, anarchy, power, security, and morality that define the realist tradition are all present in Thucydides.
(1) Human nature is a starting point for classical political realism. Realists view human beings as inherently egoistic and self-interested to the extent that self-interest overcomes moral principles. At the debate in Sparta, described in Book I of Thucydides' History, the Athenians affirm the priority of self-interest over morality. They say that considerations of right and wrong have “never turned people aside from the opportunities of aggrandizement offered by superior strength” (chap. 1 par. 76).
(2) Realists, and especially today's neorealists, consider the absence of government, literally anarchy, to be the primary determinant of international political outcomes. The lack of a common rule-making and enforcing authority means, they argue, that the international arena is essentially a self-help system. Each state is responsible for its own survival and is free to define its own interests and to pursue power. Anarchy thus leads to a situation in which power has the overriding role in shaping interstate relations. In the words of the Athenian envoys at Melos, without any common authority that can enforce order, “the independent states survive [only] when they are powerful” (5.97).
(3) Insofar as realists envision the world of states as anarchic, they likewise view security as a central issue. To attain security, states try to increase their power and engage in power-balancing for the purpose of deterring potential aggressors. Wars are fought to prevent competing nations from becoming militarily stronger. Thucydides, while distinguishing between the immediate and underlying causes of the Peloponnesian War, does not see its real cause in any of the particular events that immediately preceded its outbreak. He instead locates the cause of the war in the changing distribution of power between the two blocs of Greek city-states: the Delian League, under the leadership of Athens, and the Peloponnesian League, under the leadership of Sparta. According to him, the growth of Athenian power made the Spartans afraid for their security, and thus propelled them into war (1.23).
(4) Realists are generally skeptical about the relevance of morality to international politics. This can lead them to claim that there is no place for morality in international relations, or that there is a tension between demands of morality and requirements of successful political action, or that states have their own morality that is different from customary morality, or that morality, if any, is merely used instrumentally to justify states' conduct. A clear case of the rejection of ethical norms in relations among states can be found in the “Melian Dialogue” (5.85–113). This dialogue relates to the events of 416 B.C.E., when Athens invaded the island of Melos. The Athenian envoys presented the Melians with a choice, destruction or surrender, and from the outset asked them not to appeal to justice, but to think only about their survival. In the envoys' words, “We both know that the decisions about justice are made in human discussions only when both sides are under equal compulsion, but when one side is stronger, it gets as much as it can, and the weak must accept that” (5.89). To be “under equal compulsion” means to be under the force of law, and thus to be subjected to a common lawgiving authority (Korab-Karpowicz 2006, 234). Since such an authority above states does not exist, the Athenians argue that in this lawless condition of international anarchy, the only right is the right of the stronger to dominate the weaker. They explicitly equate right with might, and exclude considerations of justice from foreign affairs.
1.1.2 The “Melian Dialogue”—The First Realist-Idealist Debate
We can thus find strong support for a realist perspective in the statements of the Athenians. The question remains, however, to what extent their realism coincides with Thucydides' own viewpoint. Although substantial passages of the “Melian Dialogue,” as well as other parts of the History support a realistic reading, Thucydides' position cannot be deduced from such selected fragments, but rather must be assessed on the basis of the wider context of his book. In fact, even the “Melian Dialogue” itself provides us with a number of contending views.
Political realism is usually contrasted by IR scholars with idealism or liberalism, a theoretical perspective that emphasizes international norms, interdependence among states, and international cooperation. The “Melian Dialogue,” which is one of the most frequently commented-upon parts of Thucydides' History, presents the classic debate between the idealist and realist views: Can international politics be based on a moral order derived from the principles of justice, or will it forever remain the arena of conflicting national interests and power?
For the Melians, who employ idealistic arguments, the choice is between war and subjection (5.86). They are courageous and love their country. They do not wish to lose their freedom, and in spite of the fact that they are militarily weaker than the Athenians, they are prepared to defend themselves (5.100; 5.112). They base their arguments on an appeal to justice, which they associate with fairness, and regard the Athenians as unjust (5.90; 5.104). They are pious, believing that gods will support their just cause and compensate for their weakness, and trust in alliances, thinking that their allies, the Spartans, who are also related to them, will help them (5.104; 5.112). Hence, one can identify in the speech of the Melians elements of the idealistic or liberal world view: the belief that nations have the right to exercise political independence, that they have mutual obligations to one another and will carry out such obligations, and that a war of aggression is unjust. What the Melians nevertheless lack are resources and foresight. In their decision to defend themselves, they are guided more by their hopes than by the evidence at hand or by prudent calculations.
The Athenian argument is based on key realist concepts such as security and power, and is informed not by what the world should be, but by what it is. The Athenians disregard any moral talk and urge the Melians to look at the facts—that is, to recognize their military inferiority, to consider the potential consequences of their decision, and to think about their own survival (5.87; 5.101). There appears to be a powerful realist logic behind the Athenian arguments. Their position, based on security concerns and self-interest, seemingly involves reliance on rationality, intelligence, and foresight. However, upon close examination, their logic proves to be seriously flawed. Melos, a relatively weak state, does not pose any real security threat to them. The eventual destruction of Melos does not change the course of the Peloponnesian War, which Athens will lose a few years later.
In the History, Thucydides shows that power, if it is unrestrained by moderation and a sense of justice, brings about the uncontrolled desire for more power. There are no logical limits to the size of an empire. Drunk with the prospect of glory and gain after conquering Melos, the Athenians engaged in war against Sicily. They paid no attention to the Melian argument that considerations of justice are useful to all in the longer run (5.90). And, as the Athenians overestimate their strength and in the end lose the war, their self-interested logic proves to be very shortsighted indeed.
It is utopian to ignore the reality of power in international relations, but it is equally blind to rely on power alone. Thucydides appears to support neither the naive idealism of the Melians nor the cynicism of their Athenian opponents. He teaches us to be on guard “against naïve-dreaming on international politics,” on the one hand, and “against the other pernicious extreme: unrestrained cynicism,” on the other (Donnelly 2000, 193). If he can be regarded as a political realist, his realism is nonetheless not a prefiguring of either realpolitik, in which traditional ethics is denied, or today's scientific neorealism, in which moral questions are largely ignored. Thucydides' realism, neither immoral nor amoral, can rather be compared to that of Hans Morgenthau, Raymond Aron, and other twentieth-century classical realists, who, although sensible to the demands of national interest, would not deny that political actors on the international scene are subject to moral judgment.
1.2 Machiavelli's Critique of the Moral Tradition
Idealism in international relations, like realism, can lay claim to a long tradition. Unsatisfied with the world as they have found it, idealists have always tried to answer the question of “what ought to be” in politics. Plato, Aristotle, and Cicero were all political idealists who believed that there were some universal moral values on which political life could be based. Building on the work of his predecessors, Cicero developed the idea of a natural moral law that was applicable to both domestic and international politics. His ideas concerning righteousness in war were carried further in the writings of the Christian thinkers St. Augustine and St. Thomas Aquinas. In the late fifteenth century, when Niccolò Machiavelli was born, the idea that politics, including the relations among states, should be virtuous, and that the methods of warfare should remain subordinated to ethical standards, still predominated in political literature.
Machiavelli (1469–1527) challenged this well-established moral tradition, thus positioning himself as a political innovator. The novelty of his approach lies in his critique of classical Western political thought as unrealistic, and in his separation of politics from ethics. He thereby lays the foundations for modern politics. In chapter XV of The Prince, Machiavelli announces that in departing from the teachings of earlier thinkers, he seeks “the effectual truth of the matter rather than the imagined one.” The “effectual truth” is for him the only truth worth seeking. It represents the sum of the practical conditions that he believes are required to make both the individual and the country prosperous and strong. Machiavelli replaces the ancient virtue (a moral quality of the individual, such as justice or self-restraint) with virtù, ability or vigor. As a prophet of virtù, he promises to lead both nations and individuals to earthly glory and power.
Machiavellianism is a radical type of political realism that is applied to both domestic and international affairs. It is a doctrine which denies the relevance of morality in politics, and claims that all means (moral and immoral) are justified to achieve certain political ends. Although Machiavelli never uses the phrase ragione di stato or its French equivalent, raison d'état, what ultimately counts for him is precisely that: whatever is good for the state and not ethical scruples or norms
Machiavelli justified immoral actions in politics, but never refused to admit that they are evil. He operated within the single framework of traditional morality. It became a specific task of his nineteenth-century followers to develop the doctrine of a double ethics: one public and one private, to push Machiavellian realism to even further extremes, and to apply it to international relations. By asserting that “the state has no higher duty than of maintaining itself,” Hegel gave an ethical sanction to the state's promotion of its own interest and advantage against other states (Meinecke 357). Thus he overturned the traditional morality. The good of the state was perversely interpreted as the highest moral value, with the extension of national power regarded as a nation's right and duty. Referring to Machiavelli, Heinrich von Treitschke declared that the state was power, precisely in order to assert itself as against other equally independent powers, and that the supreme moral duty of the state was to foster this power. He considered international agreements to be binding only insofar as it was expedient for the state. The idea of an autonomous ethics of state behavior and the concept of realpolitik were thus introduced. Traditional ethics was denied and power politics was associated with a “higher” type of morality. These concepts, along with the belief in the superiority of Germanic culture, served as weapons with which German statesmen, from the eighteenth century to the end of the Second World War, justified their policies of conquest and extermination.
Machiavelli is often praised for his prudential advice to leaders (which has caused him to be regarded as a founding master of modern political strategy) and for his defense of the republican form of government. There are certainly many aspects of his thought that merit such praise. Nevertheless, it is also possible to see him as the thinker who bears foremost responsibility for demoralization of Europe. The argument of the Athenian envoys presented in Thucydides' “Melian Dialogue,” that of Thrasymachus in Plato's Republic, or that of Carneades, to whom Cicero refers—all of these challenge the ancient and Christian views of the unity of politics and ethics. However, before Machiavelli, this amoral or immoral mode of thinking had never prevailed in the mainstream of Western political thought. It was the force and timeliness of his justification of resorting to evil as a legitimate means of achieving political ends that persuaded so many of the thinkers and political practitioners who followed him. The effects of Machiavellian ideas, such as the notion that the employment of all possible means was permissible in war, would be seen on the battlefields of modern Europe, as mass citizen armies fought against each other to the deadly end without regard for the rules of justice. The tension between expediency and morality lost its validity in the sphere of politics. The concept of a double ethics, private and public, that created a further damage to traditional, customary ethics was invented. The doctrine of raison d'état ultimately led to the politics of Lebensraum, two world wars, and the Holocaust.
Perhaps the greatest problem with realism in international relations is that it has a tendency to slip into its extreme version, which accepts any policy that can benefit the state at the expense of other states, no matter how morally problematic the policy is. Even if they do not explicitly raise ethical questions, in the works of Waltz and of many other of today's neorealists, a double ethics is presupposed and words such realpolitik no longer have the negative connotations that they had for classical realists, such as Hans Morgenthau.
1.3 Hobbes's Anarchic State of Nature
Thomas Hobbes (1588–1683) was part of an intellectual movement whose goal was to free the emerging modern science from the constraints of the classical and scholastic heritage. According to classical political philosophy, on which the idealist perspective is based, human beings can control their desires through reason and can work for the benefit of others, even at the expense of their own benefit. They are thus both rational and moral agents, capable of distinguishing between right and wrong, and of making moral choices. They are also naturally social. With great skill Hobbes attacks these views. His human beings, extremely individualistic rather than moral or social, are subject to “a perpetual and restless desire of power after power, that ceases only in death” (Leviathan XI 2). They therefore inevitably struggle for power. In setting out such ideas, Hobbes contributes to some of the basic conceptions fundamental to the realist tradition in international relations, and especially to neorealism. These include the characterization of human nature as egoistic, the concept of international anarchy, and the view that politics, rooted in the struggle for power, can be rationalized and studied scientifically.
One of the most widely known Hobbesian concepts is that of the anarchic state of nature, seen as entailing a state of war—and “such a war as is of every man against every man” (XII 8). He derives his notion of the state of war from his views of both human nature and the condition in which individuals exist. Since in the state of nature there is no government and everyone enjoys equal status, every individual has a right to everything; that is, there are no constraints on an individual's behavior. Anyone may at any time use force, and all must constantly be ready to counter such force with force. Hence, driven by acquisitiveness, having no moral restraints, and motivated to compete for scarce goods, individuals are apt to “invade” one another for gain. Being suspicious of one another and driven by fear, they are also likely to engage in preemptive actions and invade one another to ensure their own safety. Finally, individuals are also driven by pride and a desire for glory. Whether for gain, safety, or reputation, power-seeking individuals will thus “endeavor to destroy or subdue one another” (XIII 3). In such uncertain conditions where everyone is a potential aggressor, making war on others is a more advantageous strategy than peaceable behavior, and one needs to learn that domination over others is necessary for one's own continued survival.
Hobbes is primarily concerned with the relationship between individuals and the state, and his comments about relations among states are scarce. Nevertheless, what he says about the lives of individuals in the state of nature can also be interpreted as a description of how states exist in relation to one another. Once states are established, the individual drive for power becomes the basis for the states' behavior, which often manifests itself in their efforts to dominate other states and peoples. States, “for their own security,” writes Hobbes, “enlarge their dominions upon all pretences of danger and fear of invasion or assistance that may be given to invaders, [and] endeavour as much as they can, to subdue and weaken their neighbors” (XIX 4). Accordingly, the quest and struggle for power lies at the core of the Hobbesian vision of relations among states. The same would later be true of the model of international relations developed by Hans Morgenthau, who was deeply influenced by Hobbes and adopted the same view of human nature. Similarly, the neorealist Kenneth Waltz would follow Hobbes' lead regarding international anarchy (the fact that sovereign states are not subject to any higher common sovereign) as the essential element of international relations.
By subjecting themselves to a sovereign, individuals escape the war of all against all which Hobbes associates with the state of nature; however, this war continues to dominate relations among states. This does not mean that states are always fighting, but rather that they have a disposition to fight (XIII 8). With each state deciding for itself whether or not to use force, war may break out at any time. The achievement of domestic security through the creation of a state is then paralleled by a condition of inter-state insecurity. One can argue that if Hobbes were fully consistent, he would agree with the notion that, to escape this condition, states should also enter into a contract and submit themselves to a world sovereign. Although the idea of a world state would find support among some of today's realists, this is not a position taken by Hobbes himself. He does not propose that a social contract among nations be implemented to bring international anarchy to an end. This is because the condition of insecurity in which states are placed does not necessarily lead to insecurity for individuals. As long as an armed conflict or other type of hostility between states does not actually break out, individuals within a state can feel relatively secure. He does not expect that war could ever be removed from the face of earth or banned.
The denial of the existence of universal moral principles in the relations among states brings Hobbes close to the Machiavellians and the followers of the doctrine of raison d'état. His theory of international relations, which assumes that independent states, like independent individuals, are enemies by nature, asocial and selfish, and that there is no moral limitation on their behavior, is a great challenge to the idealist political vision based on human sociability and to the concept of the international jurisprudence that is built on this vision. However, what separates Hobbes from Machiavelli and associates him more with classical realism is his insistence on the defensive character of foreign policy. His political theory does not put forward the invitation to do whatever may be advantageous for the state. His approach to international relations is prudential and pacific: sovereign states, like individuals, should be disposed towards peace which is commended by reason.
What Waltz and other neorealist readers of Hobbes's works sometimes overlook is that he does not perceive international anarchy as an environment without any rules. By suggesting that certain dictates of reason apply even in the state of nature, he affirms that more peaceful and cooperative international relations are possible. Neither does he deny the existence of international law. Sovereign states can sign treaties with one another to provide a legal basis for their relations. At the same time, however, Hobbes seems aware that international rules will often prove ineffective in restraining the struggle for power. States will interpret them to their own advantage, and so international law will be obeyed or ignored according to the interests of the states affected. Hence, international relations will always tend to be a precarious affair. This grim view of global politics lies at the core of Hobbes's realism.
2. Twentieth Century Classical Realism
Twentieth-century realism was born in response to the idealist perspective that dominated international relations scholarship in the aftermath of the First World War. The idealists of the 1920s and 1930s (also called liberal internationalists or utopians) had the goal of building peace in order to prevent another world conflict. They saw the solution to inter-state problems as being the creation of a respected system of international law, backed by international organizations. This interwar idealism resulted in the founding of the League of Nations in 1920 and in the Kellogg-Briand Pact of 1928 outlawing war and providing for the peaceful settlements of disputes. U.S. President Woodrow Wilson, scholars such as Norman Angell, Alfred Zimmern, and Reymond D. Fosdick, and other prominent idealists of the era, gave their intellectual support to the League of Nations. Instead of focusing on what some might see as the inevitability of conflict between states and peoples, they chose to emphasize the common interests that could unite humanity, and attempted to appeal to rationality and morality. For them, war did not originate in an egoistic human nature, but rather in imperfect social conditions and political arrangements, which could be improved. Yet their ideas were already being criticized in the early 1930s by Reinhold Niebuhr and within a few years by E. H. Carr. The League of Nations, which the United States never joined, and from which Japan and Germany withdrew, could not prevent the outbreak of the Second World War. This fact, perhaps more than any theoretical argument, produced a strong realist reaction. Although the United Nations, founded in 1945, can still be regarded as a product of idealist political thinking, the discipline of international relations was profoundly influenced in the initial years of the post-war period by the works of “classical” realists such as John H. Herz, Hans Morgenthau, George Kennan, and Raymond Aron. Then, during the 1950s and 1960s, classical realism came under challenge of scholars who tried to introduce a more scientific approach to the study of international politics. During the 1980s it gave way to another trend in international relations theory—neorealism.
Since it is impossible within the scope of this article to introduce all of the thinkers who contributed to the development of twentieth-century classical realism, E. H. Carr and Hans Morgenthau, as perhaps the most influential among them, have been selected for discussion here.
2.1 E. H. Carr's Challenge of Utopian Idealism
In his main work on international relations, The Twenty Years' Crisis, first published in July 1939, Edward Hallett Carr (1892–1982) attacks the idealist position, which he describes as “utopianism.” He characterizes this position as encompassing faith in reason, confidence in progress, a sense of moral rectitude, and a belief in an underlying harmony of interests. According to the idealists, war is an aberration in the course of normal life and the way to prevent it is to educate people for peace, and to build systems of collective security such as the League of Nations or today's United Nations. Carr challenges idealism by questioning its claim to moral universalism and its idea of the harmony of interests. He declares that “morality can only be relative, not universal” (19), and states that the doctrine of the harmony of interests is invoked by privileged groups “to justify and maintain their dominant position” (75).
Carr uses the concept of the relativity of thought, which he traces to Marx and other modern theorists, to show that standards by which policies are judged are the products of circumstances and interests. His central idea is that the interests of a given party always determine what this party regards as moral principles, and hence, these principles are not universal. Carr observes that politicians, for example, often use the language of justice to cloak the particular interests of their own countries, or to create negative images of other people to justify acts of aggression. The existence of such instances of morally discrediting a potential enemy or morally justifying one's own position shows, he argues, that moral ideas are derived from actual policies. Policies are not, as the idealists would have it, based on some universal norms, independent of interests of the parties involved.
If specific moral standards are de facto founded on interests, Carr's argument goes, there are also interests underlying what are regarded as absolute principles or universal moral values. While the idealists tend to regard such values, such as peace or justice, as universal and claim that upholding them is in the interest of all, Carr argues against this view. According to him, there are neither universal values nor universal interests. He claims that those who refer to universal interests are in fact acting in their own interests (71). They think that what is best for them is best for everyone, and identify their own interests with the universal interest of the world at large.
The idealist concept of the harmony of interests is based on the notion that human beings can rationally recognize that they have some interests in common, and that cooperation is therefore possible. Carr contrasts this idea with the reality of conflict of interests. According to him, the world is torn apart by the particular interests of different individuals and groups. In such a conflictual environment, order is based on power, not on morality. Further, morality itself is the product of power (61). Like Hobbes, Carr regards morality as constructed by the particular legal system that is enforced by a coercive power. International moral norms are imposed on other countries by dominant nations or groups of nations that present themselves as the international community as a whole. They are invented to perpetuate those nations' dominance.
Values that idealists view as good for all, such as peace, social justice, prosperity, and international order, are regarded by Carr as mere status quo notions. The powers that are satisfied with the status quo regard the arrangement in place as just and therefore preach peace. They try to rally everyone around their idea of what is good. “Just as the ruling class in a community prays for domestic peace, which guarantees its own security and predominance, … so international peace becomes a special vested interest of predominant powers” (76). On the other hand, the unsatisfied powers consider the same arrangement as unjust, and so prepare for war. Hence, the way to obtain peace, if it cannot be simply enforced, is to satisfy the unsatisfied powers. “Those who profit most by [international] order can in the longer run only hope to maintain it by making sufficient concessions to make it tolerable to those who profit by it least” (152). The logical conclusion to be drawn by the reader of Carr's book is the policy of appeasement.
Carr was a sophisticated thinker. He recognized himself that the logic of “pure realism can offer nothing but a naked struggle for power which makes any kind of international society impossible” (87). Although he demolishes what he calls “the current utopia” of idealism, he at the same time attempts to build “a new utopia,” a realist world order (ibid.). Thus, he acknowledges that human beings need certain fundamental, universally acknowledged norms and values, and contradicts his own argument by which he tries to deny universality to any norms or values. To make further objections, the fact that the language of universal moral values can be misused in politics for the benefit of one party or another, and that such values can only be imperfectly implemented in political institutions, does not mean that such values do not exist. There is a deep yearning in many human beings, both privileged and unprivileged, for peace, order, prosperity, and justice. The legitimacy of idealism consists in the constant attempt to reflect upon and uphold these values. Idealists fail if in their attempt they do not pay enough attention to the reality of power. On the other hand, in the world of pure realism, in which all values are made relative to interests, life turns into nothing more than a power game and is unbearable.
The Twenty Years' Crisis touches on a number of universal ideas, but it also reflects the spirit of its time. While we can fault the interwar idealists for their inability to construct international institutions strong enough to prevent the outbreak of the Second World War, this book indicates that interwar realists were likewise unprepared to meet the challenge. Carr frequently refers to Germany under Nazi rule as if it were a country like any other. He says that should Germany cease to be an unsatisfied power and “become supreme in Europe,” it would adopt a language of international solidarity similar to that of other Western powers (79). The inability of Carr and other realists to recognize the perilous nature of Nazism, and their belief that Germany could be satisfied by territorial concessions, helped to foster a political environment in which the latter was to grow in power, annex Czechoslovakia at will, and be militarily opposed in September 1939 by Poland alone.
A theory of international relations is not just an intellectual enterprise; it has practical consequences. It influences our thinking and political practice. On the practical side, the realists of the 1930s, to whom Carr gave intellectual support, were people opposed to the system of collective security embodied in the League of Nations. Working within the foreign policy establishments of the day, they contributed to its weakness. Once they had weakened the League, they pursued a policy of appeasement and accommodation with Germany as an alternative to collective security (Ashworth 46). After the annexation of Czechoslovakia, when the failure of the anti-League realist conservatives gathered around Neville Chamberlain and of this policy became clear, they tried to rebuild the very security system they had earlier demolished. Those who supported collective security were labeled idealists.
2.2 Hans Morgenthau's Realist Principles
Hans J. Morgenthau (1904–1980) developed realism into a comprehensive international relations theory. Influenced by the Protestant theologian and political writer Reinhold Niebuhr, as well as by Hobbes, he places selfishness and power-lust at the center of his picture of human existence. The insatiable human lust for power, timeless and universal, which he identifies with animus dominandi, the desire to dominate, is for him the main cause of conflict. As he asserts in his main work, Politics among Nations: The Struggle for Power and Peace, first published in 1948, “international politics, like all politics, is a struggle for power” (25).
Morgenthau systematizes realism in international relations on the basis of six principles that he includes in the second edition of Politics among Nations. Although he is a traditionalist and opposes the so-called scientists (the scholars who, especially in the 1950s, tried to reduce the discipline of international relations to a branch of behavioral science), in the first principle he states that realism is based on objective laws that have their roots in unchanging human nature (4). He wants to develop realism into both a theory of international politics and a political art, a useful tool of foreign policy.
The keystone of Morgenthau's realist theory is the concept of power or “of interest defined in terms of power,” which informs his second principle: the assumption that political leaders “think and act in terms of interest defined as power” (5). This concept defines the autonomy of politics, and allows for the analysis of foreign policy regardless of the different motives, preferences, and intellectual and moral qualities of individual politicians. Furthermore, it is the foundation of a rational picture of politics.
Although, as Morgenthau explains in the third principle, interest defined as power is a universally valid category, and indeed an essential element of politics, various things can be associated with interest or power at different times and in different circumstances. Its content and the manner of its use are determined by the political and cultural environment.
In the fourth principle, Morgenthau considers the relationship between realism and ethics. He says that while realists are aware of the moral significance of political action, they are also aware of the tension between morality and the requirements of successful political action. “Universal moral principles,” he asserts, “cannot be applied to the actions of states in their abstract universal formulation, but …they must be filtered through the concrete circumstances of time and place” (9). These principles must be accompanied by prudence for as he cautions “there can be no political morality without prudence; that is, without consideration of the political consequences of seemingly moral action” (ibid.).
Prudence, and not conviction of one's own moral or ideological superiority, should guide political action. This is stressed in the fifth principle, where Morgenthau again emphasizes the idea that all state actors, including our own, must be looked at solely as political entities pursuing their respective interests defined in terms of power. By taking this point of view vis-à-vis its counterparts and thus avoiding ideological confrontation, a state would then be able to pursue policies that respected the interests of other states, while protecting and promoting its own.
Insofar as power or interest defined as power is the concept that defines politics, politics is an autonomous sphere, as Morgenthau says in his sixth principle of realism. It cannot be subordinated to ethics. However, ethics does still play a role in politics. “A man who was nothing but ‘political man’ would be a beast, for he would be completely lacking in moral restraints. A man who was nothing but ‘moral man’ would be a fool, for he would be completely lacking in prudence” (12). Political art requires that these two dimensions of human life, power and morality, be taken into consideration.
While Morgenthau's six principles of realism contain repetitions and inconsistencies, we can nonetheless obtain from them the following picture: Power or interest is the central concept that makes politics into an autonomous discipline. Rational state actors pursue their national interests. Therefore, a rational theory of international politics can be constructed. Such a theory is not concerned with the morality, religious beliefs, motives or ideological preferences of individual political leaders. It also indicates that in order to avoid conflicts, states should avoid moral crusades or ideological confrontations, and look for compromise on the basis of satisfaction of their mutual interests alone.
Although he defines politics as an autonomous sphere, Morgenthau does not follow the Machiavellian route of completely removing ethics from politics. He suggests that, although human beings are political animals, who pursue their interests, they are moral animals. Deprived of any morality, they would descend to the level of beasts or sub-humans. Even if it is not guided by universal moral principles, political action thus has for Morgenthau a moral significance. Ultimately directed toward the objective of national survival, it also involves prudence. The effective protection of citizens' lives from harm is not merely a forceful physical action; it has prudential and moral dimensions.
Morgenthau regards realism as a way of thinking about international relations and a useful tool for devising policies. However, some of the basic conceptions of his theory, and especially the idea of conflict as stemming from human nature, as well as the concept of power itself, have provoked criticism.
International politics, like all politics, is for Morgenthau a struggle for power because of the basic human lust for power. But regarding every individual as being engaged in a perpetual quest for power—the view that he shares with Hobbes—is a questionable premise. Human nature is an unobservable. It cannot be proved by any empirical research, but only imposed on us as a matter of belief and inculcated by education.
Morgenthau himself reinforces this belief by introducing a normative aspect of his theory, which is rationality. A rational foreign policy is considered “to be a good foreign policy” (7). But he defines rationality as a process of calculating the costs and benefits of all alternative policies in order to determine their relative utility, i.e. their ability to maximize power. Statesmen “think and act in terms of interest defined as power” (5). Only intellectual weakness of policy makers can result in foreign policies that deviate from a rational course aimed at minimizing risks and maximizing benefits. Rather than presenting an actual portrait of human affairs, Morgenthau emphasizes the pursuit of power and sets it up as a norm.
As Raymond Aron and other scholars have noticed, power, the fundamental concept of Morgenthau's realism, is ambiguous. It can be either a means or an end in politics. But if power is only a means for gaining something else, it does not define the nature of international politics in the way Morgenthau claims. It does not allow us to understand the actions of states independently from the motives and ideological preferences of their political leaders. It cannot serve as the basis for defining politics as an autonomous sphere. Morgenthau's principles of realism are thus open to doubt. “Is this true,” Aron asks, “that states, whatever their regime, pursue the same kind of foreign policy” (597) and that the foreign policies of Napoleon or Stalin are essentially identical to those of Hitler, Louis XVI or Nicholas II, amounting to no more than the struggle for power? “If one answers yes, then the proposition is incontestable, but not very instructive” (598). Accordingly, it is useless to define actions of states by exclusive reference to power, security or national interest. International politics cannot be studied independently of the wider historical and cultural context.
Although Carr and Morgenthau concentrate primarily on international relations, their realism can also be applied to domestic politics. To be a classical realist is in general to perceive politics a conflict of interests and a struggle for power, and to seek peace by trying to recognize common group and individual interests rather than by moralizing.
