Why did Japanese Americans generally Face more restrictions and Italian or German Americans during World War 2?

Japanese Americans faced more restrictions during World War II primarily due to wartime paranoia and racial prejudice following the attack on Pearl Harbor. The U.S. government viewed them as potential security threats, leading to the internment of around 120,000 individuals, two-thirds of whom were U.S. citizens. In contrast, Italian and German Americans, despite facing some scrutiny, were not subjected to the same level of systemic internment due to their larger numbers and more significant political and social connections in American society. This difference reflects underlying racial biases and the historical context of U.S.-Japan relations.
