ntieth century with an emphasis placed on the changing realities of nationalism, how was the world a different place in 1945 than it had been in 1919?...

In considering the first half of the twentieth century with an emphasis placed on the changing realities of nationalism, how was the world a different place in 1945 than it had been in 1919? Briefly discuss the impact each world war had on the international community. In what specific region of the world would you argue the biggest changes had taken place? Why? Would you agree that the changes that took place from 1919 to 1945 were greater than from 1900 to 1919? Why or why not? Please provide as much information and analysis as possible to support your position.
