Me in your opinion, what was the point at which u. s. actions were no longer neutral in the 1920s through 1930s

In my opinion the point where the United States was no longer neutral was when,

president Roosevelt had started to speak against isolationism right after Japan attack in  China. They thought the effects could reach to the U.S.

They stayed neutral during 1920’s and 1930’s because they had some of their own problems in their own country. They had domestic problems example the Great depression in their  country the idea of neutrality was changing because of the president Roosevelt’s actions

the answer is prolly b
