In the early 1930s, the United States had no desire to enter another world war or become involved in European foreign affairs. America's isolationist policy was extremely popular not only with citizens but also with government officials. That being said, what factors could have contributed to the United States' involvement in World War II? . Pearl Harbor was the main factor that led the United States to become involved in World War II, despite the fact that the overwhelming majority of the country wanted nothing to do with the war in Europe. (Foner 856) “On December 7, 1941 – a date that will live in infamy – the United States of America was suddenly and deliberately attacked by the naval and air forces of the Empire of Japan. » These were the words President Franklin D. Roosevelt spoke to Congress when he asked Congress to declare war on the Empire of Japan just one day after the Japanese attack on Pearl Harbor. The same day, December 8, 1941, Congress declared war on the Empire of Japan (Pearl Harbor). Pearl Harbor is considered the most devastating “surprise attack” on American soil. But was Pearl Harbor really a surprise? There is ample evidence that supports the theory that President Franklin Roosevelt and other important American leaders knew about an attack on Pearl Harbor and did nothing to prevent it. It is said that they did this because FDR was determined to help England win the war and reap the glory. Since the idea of ​​going to war is unpopular, something drastic would have to happen to change America's attitude toward foreign affairs. Pearl Harbor was their opportunity (Stinnett 15). The first piece of evidence that supports this theory is the fact that the United States had broken the Japanese...... middle of paper ......n to fight which, many This is the reason why Franklin Roosevelt allowed it to happen. Although very few, if any, have accused him of planning the attack, the theory that he allowed it to happen as a "means and an end" is becoming increasingly popular. Regardless of FDR's involvement, it is clear that the attack on Pearl Harbor was a key factor in pushing the United States into World War II.
