Answer 1

The direct cause of the U.S. entry into World War II was the bombing of Pearl Harbor on December 7, 1941, by the Japanese Navy. This surprise attack led to the United States declaring war on Japan the following day, which subsequently prompted Germany and Italy to declare war on the U.S. a few days later.
