Septemmarks the formal surrender of Japan in World War Two which took place aboard the USS Missouri in Tokyo Bay. Roosevelt proclaimed Decemas, “a date which will live in infamy.” After years of a global conflict, the United States had officially entered into World War II.

As a result, on December 11, 1941, Germany and Italy retaliated with a declaration of war on the United States, as they were allied to Japan under the Tripartite Pact (or the Axis Pact) of 1940. On December 8, 1941, just one day after the attack, the United States declared war on Japan. The attack on Pearl Harbor was essentially the breaking point. Up until this point, America had isolated itself from the conflicts in Asia and Europe, but over time, these conflicts had built unimaginable tension. Prior to the attacks on Pearl Harbor, the United States had maintained formal neutrality in the global escalation of conflict. Significance of Pearl Harbor to the United States’ WWII Involvement Japan also hoped to severely cripple American morale, aiming to hinder their acceptance of the war and diminishing overall U.S. The hope was that the surprise attack would devastate the power of the United States Navy and allow valuable time for Japan to strengthen its own naval capabilities once the war with the Unites States had been engaged. Pacific Naval Fleet before an announcement of war was even made. The December 7th attack was carried out with the intention of destroying the U.S. By late 1941, many Americans expected war with Japan to be imminent, though they had no idea it would begin with such a sneak attack. In response to their aggression, the United States placed strict embargos on Japan, which brewed hostility between the two countries. The Japanese had been unsuccessfully negotiating with the United States in the hopes of continuing expansion within Southeast Asia, namely the Philippine Islands (an American Territory at that time), Dutch West Indies, and Malaysia.

The Japanese began invading China in 1931, and this was when the war began to brew. Prior to the Pearl Harbor attack, World War II had been going on for almost ten years in China and two years in Europe. Many schools and museums have activities to educate students and the public on the historical importance of Pearl Harbor. Pearl Harbor survivors, associations and the military community typically commemorate the day with memorial services, wreath laying ceremonies and the retelling of the days’ events. The White House and all United States government buildings fly the American flag at half-mast as should all homes and private buildings to honor those who died in the attack at Pearl Harbor. Pearl Harbor will be remembered Tuesday, December 7, 2021. The Japanese aircrews managed to achieve complete surprise and for two hours, Japanese fighter, bomber and torpedo planes carried out a shocking assault on the naval base. Just before 8am on the morning of December 7, 1941, hundreds of Japanese fighter planes carried out a devastating attack on the Pearl Harbor American Naval base in Honolulu, Hawaii, on the island of Oahu.
