Japanese Internment Camps- over 100,000 Japanese-Americans where rounded up and put in "Internment Camps", which were poorly made barracks surrounded by machine guns and razor wire. The prisoners in the camps where not found guilty of a crime but were thought to be a threat to national security. life in the internment camps was very bad .
I think that what happened at Pearl Harbor made every body realize that you cant stay isolationist when a war is going on in you backyard.
