  Too many people don't seem to understand what that is.

  The same was in movies of the era.
  The production code didn't allow for any blood when someone was shot. 
You could have someone in a white tuxedo be riddled with bullets in a gang war
and no blood was to be seen.
  In the '60s when the code was relaxed or completely done away with,
someone is shot with a .22 and blood is all over the place.
  From one extreme to the other.
  The code continued on in tv shows where someone is blown away and there's
nothing.  Maybe a little red dot, if that.
   While some complain about cartoon violence nothing, or very little, is
said about the real aftermath of a violence act.

  The Germans are ragged on all the time (Nazi this, Nazi that) but Japan
is given pretty much a free ride.  They were as bad or worse than the Nazi's
is many ways.
  In German schools kids are taught about that time.  Japan?  Its skimmed
over.
  And the emperor never admitted Japan had lost, but merely "the war didn't
go as we planned", or words to that effect.
