You are totally right, Motley that was a terrific mistake on Warren's part, even the FBI warned him it was wrong and unneeded.  Hundred of thousands of innocents suffered.
But to suggest my little friend and  his family had anything to do with your cousin on the Arizona is  just bananas.  
And having had two uncles and a cousin as Marines in the Pacific  I know a little about Japanese  WWII atrocities and am  happy that most of today's Japanese deplore them, even may feel "guilty" if you'll pardon the expression.  (except, perhaps, Mr. Trump's new buddy Abe.)
