Quote from AAAintheBeltway:
Of course, Bush manipulated us into Iraq. No doubt they construed ambiguous intelligence in the most negative way and downplayed other data that undermined the case. But Presidents always do that.
FDR clearly wanted the US in WW II and did his best to make it happen. Clinton was not exactly truthful about what was happening in Kosovo and Serbia, when he was trying to manipulate public opinion to justify that war. The Spanish-American War was undertaken under dubious justification, as I recall.
But there is a vast difference between marshalling evidence in a way that supports your case and lying. There is a strong case to be made that Bush made a big mistake and that he misconstrued the evidence. History will judge him harshly for that, no doubt. What turns a lot of people off however, is the constant refrain that "Bush lied", when there is zero evidence to support that charge.
