Foreign policy varies between isolationism and internationalism. Isolationism means a country keeping to their own borders. Internationalism means a country works with other countries. 

Following World War I, the US attempted to return to a form of isolationism. They were wanting to keep out of European affairs and formed world agreements to keep out of the war. Until the attack on Pearl Harbor, the US would attempt to maintain neutrality. Franklin Roosevelt passed neutrality act in 1935, 37, and 39 stating the US could not engage in trade with warring nations.
