The impact of Pearl Harbor

The attack on Pearl Harbor had a huge impact on the United States. Before this event, the country was immersed in a stage of naivety, isolationism and wear and tear after years of war. However, the Japanese sneak attack woke the nation from its slumber, profoundly impacting its collective psyche. The shock and devastation caused by the attack are, to this day, considered the worst military defeat in US history.

According to renowned war historian Robert Citino, “No time in American history casts a longer shadow than Pearl Harbor.” Remembering this fact has become a national imperative, a patriotic duty ingrained in the American people. The act of remembrance has become a media and political ritual, repeated countless times, forming an integral part of our community life.

Japan and its expansion in the Far East

Since the late 1930s, Japan had sown death and destruction in the Far East, invading China and looting its cities. Faced with this threat, the US leadership headed by Franklin D. Roosevelt decided to impose economic sanctions as punishment and stop the Japanese empire’s expansion. However, these measures failed to contain Japan’s actions definitively.

The lack of natural resources was a challenge for Japan, which needed rubber, tin, and oil to continue its war effort. The gaze of the Japanese military command was then focused on the US naval fleet located at Pearl Harbor. In order to prevent the United States from intervening in the war in the Pacific, the Japanese carried out a daring plan. They slipped stealthily six aircraft carriers, accompanied by an assorted group of escort ships and submarines, approximately 3,000 miles to the shores of Hawaii.

The surprise attack on Pearl Harbor

On December 7, 1941, on a beautiful, quiet Sunday morning, the Japanese naval force surprised the United States with an impressive display of fighters, bombers, and torpedo planes. The American fleet was taken by surprise and left defenseless. In just 90 minutes, the Japanese overran the fleet, destroying 19 ships and 300 aircraft and taking the lives of more than 2,400 Americans.

This heinous attack aroused the spirit of resistance in the United States. The War Department feared that Japan would attack the mainland along the west coast. The population swore revenge, and tens of thousands of people rushed to join the Army, Navy and Marine Corps. Roosevelt energetically addressed Congress, further stoking the desire for retaliation. The thirst for revenge drove the nation to war, and that determination was passed down through multiple generations.

Hence the rallying cry “Remember Pearl Harbor!” will always resonate in the memory of the nation as a constant reminder of the need to remain firm in the face of threats that may arise.
