Which event on December 7, 1941 brought the United States into World War II?

• A. Battle of Britain
• B. Fall of France
• C. German Invasion of Poland
• D. Pearl Harbor

Answer: (D)

A surprise attack on Pearl Harbor on December 7, 1941, drew the United States into World War II. The strike targeted the U.S. Pacific Fleet in Hawaii, aiming to cripple American naval power and curb U.S. interference as Japan expanded across Asia. The shock and scale of the attack turned isolationist sentiment into a mandate for war, and Congress soon declared war on Japan. In the days that followed, Germany and Italy declared war on the United States, committing the nation to fight in both the Pacific and European theaters. Other major events like the invasion of Poland, the fall of France, and the Battle of Britain were pivotal in the war, but they occurred before the United States entered the conflict.
