How did the united states react to the rise of expansionist dictatorships in europe and asia

The U.S government reacted to the rise of expansionist dictatorships in Europe and Asia by developing and authorizing the neutrality acts.

Explanation:

This made ammunition and war materials to belligerent nations. That way the government guaranteed that the U.S. would not be involved in another major conflict after the losses of World War 1. It was a very wise decision because that way many of the troubles of the second world war were avoided until it was required that the U.S. had to take action. Also, it provided a peaceful environment until foreign powers damaged the U.S. Because it was until they attacked the U.S. that the U.S. got involved in the war.
