The Battle of Midway Island was a key turning point in the war in the Pacific Ocean during World War II. Japan had been able to conquer almost all of the western Pacific Ocean and most of the central Pacific Ocean regions after the attack at Pearl Harbor. Since a significant portion of the American navy and air force were damaged at Pearl Harbor, and since the army also took a significant hit, there was little opposition to stop the Japanese advances in the Pacific Ocean and in Asia. The Japanese had their sites set on Midway Island, then the Hawaiian Islands, and possibly the west coast of the United States.
These plans were destroyed after the Japanese defeat at the Battle of Midway Island. As a result of the Allied victory at Midway Island, Hawaii was now safe from attack. Since Japan lost most of its navy and aircraft carriers in its failed attack on Midway Island, Japan would never again go the offensive in World War II. After this battle, Japan was forced to begin to retreat from the areas they gained. The Allies implemented their plan of island hopping. Under this plan, the Allies slowly regained islands they lost, one at a time, until we were close enough to begin bombing Japan. Eventually, the decision was made to use the atomic bombs, which ended World War II.
