Step-by-step explanation:
B) Destroy ships and planes that threatened their expansion efforts. The Japanese attacked Pearl Harbor on December 7, 1941, with the aim of destroying the U.S. Pacific Fleet, which they viewed as a potential threat to their planned expansion in the Asia-Pacific region. The attack was a surprise military strike on the U.S. naval base at Pearl Harbor, Hawaii, and was a key factor that led to the United States' entry into World War II.
