The desire to reduce cognitive dissonance may also be skewing some Americans' memory of the government's rationale for going to war. Asked, "Thinking back to when the US government was making the case for going to war with Iraq, according to the government, what was the most important reason for going to war with Iraq?" 60% said "the evidence that Iraq had weapons of mass destruction," and 19% said "the evidence that Iraq was working with the terrorist group al'Qaeda." But 20% said the most important reason was "the fact that Saddam Hussein was an oppressive dictator." Asked for the second most important reason, another 32% chose "the fact that Saddam Hussein was an oppressive dictator," while weapons of mass destruction were chosen by 24% and links to al'Qaeda by 42%.
