The rise of dictatorships
and the desire of Germany, Italy, and
Japan
was one reason why Japan attacked Pearl Harbor. Another
reason why the Japanese attacked Pearl Harbor is because the
Japanese and the U.S. were the only powerful forces in the
Pacific. Japan thought that if they destroyed Pearl Harbor,
the U.S. would move out of the Pacific, and then Japan would
be the only strong fighting force in the Pacific, and they
could easily conquer the Pacific.
The United States military dropped the Atomic Bomb at Hiroshima so that Japan would surrender. The Japanese did not surrender in the next three days so the U.S. dropped the second Atomic Bomb on Nagasaki. After that, the Japanese surrendered and exited the war.
