Question

Quizplus · Accepted Answer

A large number of people believed that Japanese Americans were potential sources of espionage and subversion, and this fear was fueled by the attack on Pearl Harbor and anti-Japanese sentiment during World War II. The decision to intern Japanese Americans was also influenced by political pressure and racism towards people of Japanese ancestry. There was no evidence that Japanese Americans posed a threat to national security, and the placement of prison camps was not strategic in preventing air attacks. Additionally, the internment included women and children, and was not related to draft registration.
