Define, compare, and contrast isolationism and internationalism. When has the United States pursued each type of foreign policy?

How did internationalism differ under the grand strategies pursued during the Cold War and during the George W. Bush administration? Has Barack Obama's foreign policy focused more on isolationism or internationalism? Provide two pieces of evidence to support your argument. In your opinion, should U.S. foreign policy be more isolationism or internationalist? Why?

What will be an ideal response?

An ideal response will:
1, Define isolationism as the belief that the United States should stay out of world affairs.
2, Define internationalism as the belief that the United States should actively engage in world affairs.
3, Identify the main similarity between isolationism and internationalism, which is that both are grand strategies that dominated U.S. foreign policy at one time.
4, Identify the main difference between isolationism and internationalism, which is that they are essentially opposites. Isolationists want the United States to stay out of world affairs, while internationalists want the United States to be heavily involved.
5, Note that isolationism held sway prior to the twentieth century, but that internationalism has been dominant ever since.
6, Outline the internationalist grand strategy of containment during the Cold War, in which the United States played an active role in containing communism.
7, Explain the internationalist grand strategy of the Bush Doctrine, which said that the United States should preemptively attack countries if they are viewed as a potential risk.
8, Argue that Obama's foreign policy is more internationalist. Two examples of Obama's internationalist foreign policy are the military involvement in Libya and in Afghanistan.
9, Make and defend an argument for either isolationism or internationalism.
