On December 7, 1941, Japan launched a surprise military strike against the United States naval base at Pearl Harbor in Hawaii, leading the U.S. to enter World War II.

Key figures in this event included Admiral Isoroku Yamamoto, who masterminded the attack, and U.S. Navy Captain Frank Jack Fletcher, who commanded the fleet defending Pearl Harbor. The attack resulted in significant damage to the U.S. Pacific Fleet.

The attack galvanized American public opinion, which had been largely isolationist prior to the bombing, and led to a united national resolve to fight in the war.

Pearl Harbor Day is remembered annually, where survivors and their families gather to commemorate those who lost their lives.

The attack led to the U.S. declaring war on Japan the very next day, thus entering World War II.

A little-known fact is that while the attack damaged many ships, the U.S. aircraft carriers were not at Pearl Harbor at the time and thus escaped destruction.

The code name for the attack was 'Operation AI,' and it was meticulously planned over several months, with Japan aiming to eliminate U.S. naval power in the Pacific.

Despite the attack, the Japanese underestimated American resolve, which ultimately led to their defeat and the dropping of atomic bombs on Hiroshima and Nagasaki.

What do you think was the most significant impact of the Pearl Harbor attack on America's future?
