Question

under executive order 9066, the military
could remove people considered a threat from their homes.
was assigned to defend california from threats from the pacific.
rebuilt pearl harbor and hawaii after the japanese attack.
began to fight with allied forces in japan.

Explanation:

Executive Order 9066 was issued during World War II. It authorized the military to remove people (specifically Japanese - Americans) considered a threat (due to unfounded fears of espionage) from their homes on the West Coast. The order was not about defending California from Pacific threats in a traditional military - defense - assignment sense (it was more about internal, discriminatory displacement). Rebuilding Pearl Harbor and Hawaii was not the main purpose of this order. And it had nothing to do with fighting with Allied forces in Japan.

Answer:

"could remove people considered a threat from their homes."
