Why is the United states could of stayed out of world war 2?

The United States could have potentially stayed out of World War II due to its initial isolationist sentiment, driven by the desire to focus on domestic issues and avoid the devastation of European conflicts. The Neutrality Acts of the 1930s reflected this stance, limiting U.S. involvement in foreign wars. Additionally, strong public opinion favored non-intervention, and the Atlantic Ocean provided a natural barrier against direct threats. However, events like the attack on Pearl Harbor in December 1941 ultimately shifted public and political opinion, compelling the U.S. to join the war.
