Question

4) Why did Japan attack the United States in 1941?

Answer 1

By attacking Pearl Harbor Japan believes that it can severely cripple the U.S fleet and buy them time in the Pacific and Southeast Asia. So not only would they be able to launch their attacks without interference from the U.S they would also have time to dig in defensively and consolidate their gains.

Answer 2

Answer: Japanese leaders were concerned about the need for natural resources, including oil.
