What event led the United States to enter World War II?

• A. The Attack on Pearl Harbor on December 7th, 1941
• B. The Invasion of Poland by Germany
• C. The D-Day invasion
• D. The Battle of Midway

Answer: (A)

Direct aggression against the United States at a time of global conflict is what pulls the country into war. The surprise attack on Pearl Harbor in Hawaii on December 7, 1941 demonstrated a direct threat to U.S. national security and broke the U.S. stance of neutrality. In response, the United States declared war on Japan the next day, and soon after Germany and Italy declared war on the United States, bringing the country into World War II. Other events were significant in the war’s progression, but they did not by themselves cause the United States to enter the conflict.
