Answer:
Japanese bombed the American naval base Pearl Harbor
Step-by-step explanation:
On December 7, 1941, the Japanese launched a surprise attack to Pearl Harbor, Hawaii, which destroyed 21 US ships, over 300 aircraft, killed 2,400 people and hurt 1,000 Americans.
The following day, the U.S. President Franklin D. Roosevelt delivered the famous Infamy Speech to a Joint Session of the Congress, asking to declare war on Japan, and in which he declared December 7 “a date which will live in infamy”, referring to the Pearl Harbor Attack.
