Why might have the us stay out of World War 1 until 1917?

The United States initially stayed out of World War I due to a strong isolationist sentiment among the American public and government, which favored avoiding European conflicts. Economic interests also played a role, as the U.S. was trading with both the Allies and Central Powers, benefiting from neutrality. Additionally, events such as the Lusitania sinking and unrestricted submarine warfare by Germany did not sufficiently sway public opinion until the later years of the war, when the threat to American security and interests became more pronounced, leading to U.S. entry in 1917.
