Question

Which factor explains the rise of isolationist sentiment in the United States following World War I?

Answer 1

The threat of communism on American ideals caused them to be very isolationist towards Europe and the rest of the world.
Known as the Red Scare.

Answer 2

Answer:

The loss during world war one and the Great depression were the major factors for the United States to stay out of world affairs. During the 1930s the US followed the policies of Non-Interference as it was during the president ship of Benjamin Franklin. The Pacific ocean and its distance from Europe and Asia acted like free security for it. The US rejected the league of nations and there was no official statement about the Ethiopian Invasion and Spanish civil war.

Another major factor for isolationist policies of the US was the dominance of the isolationist inside the congress which thwarted all the attempts made by  Roosevelt to intervene in international affairs. The isolationists in the US congress included Business owners, Peace Activists, and Conservatives. the worsening condition of Europe in the 1930's didn't lead to the break from isolationist policies. It was only after the Pearl Harbor attack that the US gave up its foreign policy of isolation.ed
