Explanation:

After the December 7, 1941 Pearl Harbor attack, the U.S. abandoned isolationism. Evacuations of West Coast citizens (Japanese Americans) happened later, and immediate direct attacks on Japan were not launched right away. The U.S. Congress formally declared war on Japan on December 8, 1941, the day after the attack.

Answer:

Congress declared war on Japan the next day.
