If this story is true, why would the boy "roll his eyes" when asked by his mother who shot him down?  The Japanese:rolleyes: 
He would have called them Japs, if it was a recollection, especially from a fighter pilot, he woulda wanted to kill them with a vengence and hated their guts.
Sorry, I don't buy this story.  A two and a half year old toddler would not be PC and using PC terms.  He would tell it like it is.
