In the land of the free we have lots of hupla about comparisons of Bush with Hitler from the RNC. You may enjoy Cockburn's take on this:
"My problem with the Hitler-Bush pairing is not so much the comparison per se which is solidly in the respectable mainstream of political abuse, but in the strange hysteria of Democrats about Bush as a leader of such consummate evil, so vile that any Democrat would be preferable. Any Democrat? George Bush is by definition a warmonger, but Wesley Clark, one of the contenders for the Democratic nomination, actually issued an order that could have sparked Armageddon."
