Did they also made German camps, and Italian camps? Surely the other axis countries would have supporters in American soil wouldn't they? Or was is something especially racist against Japanese?
Definitely too late, the victims of the State segregation are mostly gone by now...
They did not allow Germans or Italians to have a ham radio.
They did not jail them.
Having some Italian ancestors I am pretty sure of this to be a fact.
Japanese owned some good pieces of land in California some of it was stolen. So it was a land grab more than anything.
