Events like the rise of Hitler, Roosevelt's oil sales decision to Japan, and the Russian Revolution influenced US entry into the war.
Events that shifted US policy on entering the war stemmed from various factors. Initially, President Wilson embraced neutrality, focusing on economic power's influence on the conflict. However, as the war progressed in Europe and American trade with the Allies surged, public debates on military preparedness intensified.
The US entry into the war was significantly impacted by the rise of Hitler and his aggressive actions in Central Europe. With Roosevelt's decision to cut off oil sales to Japan, tensions rose, leading to the breakdown of trade partnerships and eventually triggering US involvement.
The ongoing Russian Revolution and the emergence of the Bolsheviks also played a role in influencing US government policy. These events, alongside escalating conflicts and strategic decisions made by various world leaders, collectively contributed to the shift in US stance towards entering the war.
