In all fairmess
The US nor any other govt. cared a fig about the Nazi death camps until the end of the war, and they had positive intel of their existance very early in the war.
Also, Bush did in fact talk about, from the very beginning, about removing saddam's tyranny from Iraq. In fact ending saddam's tyranny over Iraq was official American policy since 1998.
The fact that we are more focused on the mass graves now than at the beginning of this war does not in any way invalidate our sincere and appropriate concern over them now.
