Today marks the 75th anniversary of the Japanese attack on Pearl Harbor. On December 7th, 1941, the Japanese navy attacked the United States naval base at Pearl Harbor, Hawaii. This event is what led to the United States entry into World War II.
The attack was meant to be a preventive measure to ensure that the US Pacific fleet would not interfere with Japanese plans to attack overseas territories. The US had moved their fleet from San Diego to Pearl Harbor prior to that to discourage Japanese aggression in the Far East. 2,403 Americans died as a result of the attack. The following day, the United States declared war on Japan. Later, Nazi Germany and Fascist Italy would declare war on the US and vice versa.
Franklin Delano Roosevelt, President of the United States, declared December 7th, 1941, a “day which will live in infamy”. The attack was declared at the Tokyo Trials to be a war crime because of its unexpected nature.
