How did the world wars change the way Americans think and behave?

Answer:

Answer

The World Wars, especially the Second, transformed American foreign policy from highly isolationist to world superpower and heavily expansionist. Not expansionist in the more traditional imperial (aka. we militarily conquer and subdue other nations) sense of the word, but rather in an economic and ideological sense---mostly to stop Soviet expansionist policy.
