What happened to Japanese-Americans at world war II?

My own experience (American) when I lived in Berkeley after the war, was that my neighbors were of Japanese decent, and they all in the Bay Area were arrested (with no cause, other than birthright) and imprisoned in Nevada for a number of years! Their property was confiscated--stolen, and they had to live in that desolate dry, dusty land! They were shipped there and guarded by US soldiers! They had to build their own barracks and to work. I don't remember how many years this went on--until the end of the war, certainly, and there had NEVER BEEN ONE INSTANCE OF SABOTAGE! The whole thing was a land-grab, where Caucasian Americans stole their homes and property! When they were released, they returned and strangers were living in their homes! They finally rec'd some small compensation, but nothing compared to what had been stolen from them! I think that some General was behind all of this, but can't remember. There were similar camps in Colorado and other States--all in arid wasteland. A SHAMEFUL EPISODE IN AMERICAN HISTORY.--OH YES! The young men enlisted in the US Army and served in one unit in Europe with distinction!
