No doubt, most people, knowing the truth, would not go for an unjustified war when the outcome is so predictably disasterous (both for the US and the Iraqis).
I think it is important to note though that the neocons (and AIPAC) are not driven solely by war profits (although this is a big part of it for them and others). There is a definitive link with Israel's right-wing which is driven in large part by ideology, including messianic Jewish fundementalism. These are things we are not supposed to talk about, but they are alsolutely true. You can sense the ideological hatred in people like Daniel Pipes.
