Order 9066 was a World War 2 policy that had long term consequences for the Japanese Americans. The order allowed the Army to "evacuate" anyone that they thought was a threat to National Security.
It affected the Japanese Americans severely. The order forced more than 120,000 Japanese to relocate. They were relocated to 1 of the 10 internment camps around the U.S. (Internment = putting someone into some sort of prison..) They put the Japanese into these camps in fear that they were loyal to Japan.
The United States eventually won the war. This showed other countries that even in the worst situations the country could hold it's own.
