What happened that made america reluctant to enter ww1?

America's reluctance to enter World War I stemmed from a strong isolationist sentiment among its citizens, who were weary of foreign conflicts after the devastation of the Civil War. The country prioritized domestic issues and maintained a policy of neutrality, influenced by diverse immigrant populations with ties to both the Allied and Central Powers. Additionally, incidents like the sinking of the Lusitania in 1915 and unrestricted submarine warfare by Germany raised concerns but did not immediately compel the U.S. to join the conflict. It wasn't until the interception of the Zimmermann Telegram and ongoing attacks on American ships that the U.S. shifted towards intervention in 1917.
