The U.S. remained neutral in the early years of WWII. The direct trigger for its entry was the Japanese surprise attack on Pearl Harbor on December 7, 1941. The U.S. declared war on Japan the following day, officially entering the conflict. The other events listed occurred earlier in the war, before U.S. involvement.
