Final answer:
During World War II, over 300,000 Japanese Americans were sent to internment camps as a result of fears of espionage. Around 120,000 Japanese Americans were detained in these camps on the West Coast for the duration of the war.
Step-by-step explanation:
During World War II, after the U.S. entered the war, over 300,000 Japanese Americans were sent to internment camps. This decision was made in response to fears that Japanese Americans might spy on U.S. military installations. Around 120,000 men, women, and children of Japanese descent were detained in these camps on the West Coast for the duration of the war.
In a demonstration of loyalty to the United States, over 30,000 Japanese Americans joined the war effort, including the highly decorated 442nd Regimental Combat Team. Regrettably, military service did not exempt their families from internment. The policy of internment was later acknowledged as the result of "race prejudice, war hysteria, and a failure of political leadership," and reparations were eventually made to survivors.
