It is hard to say Bush is worst ever by using the Iraq war as your evidence considering the Vietnam War ended just 32 years ago, killed 30x as many Americans, was more costly, far more futile, and led to a despondency and apathy amongst Americans which was epitomized by the Carter presidency and the can't-do foreign policy (see Iran hostage situation). To say that Bush is "worst ever" based on war policy is to completely ignore Johnson/Nixon in Vietnam, Johnson being the extreme example of a Prez out of touch with reality, having no plan to deal with the situation, literally sitting at his desk and picking bombing targets himself. People this quick to point to Bush really have no understanding of history, and I'm not a Republican. Of course, intelligent discussion requires more than just an ISP address, which is thus the downfall of great debate on the internet.
