I have never disputed the facts you cite. I do however dispute that all Japanese-Americans were considered spies and treated as such.
All were up-rooted from their homes and most possessions but I am sure that the vast majority were then relocated inland to locations as Granada, Colorado. Prior to the final move there were bleak "reception and assembly centers." I am in no way claiming that it was a "picnic."
I am suggesting that relatively few went to camps like Tule Lake, California. I believe that was a true internment camp.
You are correct in assuming that I am no expert in this. But I was old enough back then to remember a little bit about W.W.II and of course I have read a little about this aspect. I have absolutely no problem with President's Truman's decision to end the War with atomic bombs BTW. I do remember that.
The camp near Granada "contained several schools, a hospital, and a police department. Agriculture was the principal industry; vegetable and grain crops, along with livestock, were raised on two ranches . . . The evacuees themselves were responsible for much of the community's government."
I remember reading that in some cases the people decided to remain with the community (not necessarily Granada) and not go through the hassle of starting over in their old communities. I can believe it true or not.
Only West Coast Japanese were relocated. I knew someone who as a 12 year old boy was sent to live with his grown sister in Chicago. His parents went to the internment camps.
