Why did the US government interfere with Japanese Americans?

The U.S. government interfered with Japanese Americans during World War II primarily due to fears of espionage and sabotage following the attack on Pearl Harbor in 1941. This led to the implementation of Executive Order 9066, which resulted in the forced relocation and internment of around 120,000 Japanese Americans, two-thirds of whom were U.S. citizens. The decision was driven by racial prejudice, wartime hysteria, and a lack of political will to protect the rights of these individuals, despite the absence of evidence supporting the claims of disloyalty. This action has since been widely condemned as a violation of civil liberties.
