2000s Preemptive War

At Issue is the question, does preemptive war reduce terrorism?  Anticipatory self-defense, or thedoctrine of preemption, holds that it is acceptable for a state to attack a known hostile enemy before thatenemy can attack it. Although prohibited by the United Nations Charter in 1945, anticipatory self-defensewas necessary throughout the twentieth century, and it continues to be into the twenty-first. With theproliferation of weapons of mass destruction, to wait to be struck first could be devastating. Many inpower believe that preemptive war is thus key to the security of the United States and is a legitimateoption to reduce global terrorism.The Bush Doctrine, as promulgated by President [George W.] Bush following the events of September 11[2001, when terrorists flew planes into the World Trade Center and the Pentagon], contemplatespreemptive use of force against terrorists as well as the states that harbor them. If the United NationsCharter is to be believed, however, carrying out that doctrine would be unlawful.  In your essay, take aposition pro or con the belief in the correctness of preemptive war.
