Well I rather doubt if Timothy McVeigh really thought he was going to get away with it, even though he didn't stick around to get blown up. He was a sort of delayed action suicide bomber.

And Paul Hill wasn't a bomber, but after killing the abortion doctor and his body guard, he stuck around and handed himself in, and didn't appeal against the death sentence.

Again, the IRA Hunger Strikers weren't suicide bombers, but there was a lot of common ground in the mindset involved.

If democracy can manage to work in the USA, with all its histiorcal baggage, and in a Europe, where a generation ago fanatics were running extermination camps, there's no reason it shouldn't work in somewhere like Iraq. "Western style" - which "Western style" would that be? Texas or Sweden or France or Italy or Israel? Democracy in Iraq would surely be as different from any of these as all of these are from each other.
