Which event directly led the United States to enter World War II in 1941?

• A. D-Day invasion
• B. Atomic bombings of Hiroshima and Nagasaki
• C. Pearl Harbor
• D. Battle of Midway

Answer: (C)

Pearl Harbor is the event that pulled the United States into World War II in 1941. The surprise attack on December 7, 1941, targeted a major U.S. military base in Hawaii and showed that Japan intended to fight a war against the United States. In response, the United States declared war on Japan, which brought the U.S. into the conflict across both the Pacific and, after Germany and Italy declared war on the United States, the European Theater as well. The other events happened later or in a different context: D-Day is the Allied invasion of Normandy in 1944, after the United States had already entered the war; Midway was a 1942 battle that shifted momentum in the Pacific but occurred after entry; and the atomic bombings in 1945 contributed to Japan’s surrender, not to U.S. entry into the war.
