The US, the younger and stronger who spent the very long time to develop itself and observe Europe, had to enter into world affairs to end the wars and show its power. During the European major power competing and declaring the war against one other, US had its one hand developed its power and perfecting democracy and another hand boosting its values against the Europeans’. There were two contradictory concepts about the US foreign policy-the Isolationism and Globalism. For the isolationist, America should not engage in international affairs.
It should try to perfect itself and act as the model to the world. The Globalist, in contrast, argued that America has to go to international and bring its value to the rest of the world. America could not stay as neutrality if it wishes to become the superpower, and the American interest is lying in the international arena. The US was the major power, as the major power it must have obligations and deal with international issues. As Theodore Roosevelt argued:
“To us as a people it has been granted to lay the foundations of our national life in a new continent … Much has been given us, and much will rightfully be expected from us. We have duties to others and duties to ourselves; and we can shirk neither. We have become a great nation, forced by the fact of its greatness into relations with the other nations of the earth, and we must behave as beseems a people with such responsibilities”.
