Explanation:

The U.S. remained neutral in WWII until a direct, large-scale attack on its military base. Japan's surprise attack on Pearl Harbor on December 7, 1941, resulted in significant American casualties and destruction, prompting the U.S. to declare war on Japan the next day, officially entering WWII. The other events did not trigger U.S. entry into the war.

Answer:

Japan's attack on Pearl Harbor
