Quote:In the course of the war, the federal government registered around half a million “enemy alien” civilians, spied on many of them, and sent approximately 6,000 men and a few women to internment camps. Perhaps more strikingly, it seized huge troves of private property with dubious relevance to the war effort, ultimately amassing assets worth more than half a billion dollars—close to the entire federal budget of pre-war America.
