"Why do the Japanese and the Nazis hate us"?
What a sight that would be. I can see 200 Nazi SS Officers, all lined up like ducks in a row and ready for bombing. When all of a sudden General Patton says: "Wait, those men are standing on sacred Nazi cemetaries. Let them be, we'll deal with them later".
Truth be told, if we had in the White House and Senate during WWII what we have now, you and I would be speaking Japanese or German, or both.
