World War II was one of the greatest wars America was ever involved in. It all began with Germany's invasion in Poland and multiple European countries around Germany. As Germanys blitzkriegs progressed, more and more countries became involved in the war, except for America. Before the United States was involved with the war, Allied forces were struggling against the powerful axis powers. However, as soon as America helped its allied forces, the tables turned rapidly. America was eventually led into the war because of the Pearl Harbor attack, the aid it was providing to Allied nations, and the rise of the axis powers. .
One of the main reasons why America became involved in the war was because of the Pearl Harbor attack. However, the Pearl Harbor bombing was a result of the issues between American and Japan. Before Japan invaded Pearl Harbor, it invaded Manchuria, China. America became angry at Japan for attacking China and threatened to stop trading oil with Japan if it did not stop. The Japanese refused to stop invading China, so America halted oil trade with the Japanese. As a result, on November 26, 1940, a Japanese fleet carrying fighter planes bombed Americas main naval base in Hawaii, Pearl Harbor. Americans were all caught off guard and numerous battleships were destroyed, including the USS Arizona. Since Americas main naval base was destroyed, the Japanese had many easy victories in the Pacific. This led to an uproar in America and almost everyone wished for retaliation against Japan. .
Besides being butchered by Japan, America was also led into the war because it was already aiding other countries that were fighting against the Axis powers. During the war, the British government had a very low amount of money to purchase weapons, so America decided to help them out. Franklin D. Roosevelt then abandoned its cash and carry policy and replaced it with a lend-lease policy. This meant that America would lend goods to Britain and the British would return or replace the goods after the war is over.
