I don't think Bush or Blair should be killed. I have severe problems with them both, but I don't think they should be executed. I don't think anyone should be executed. Why did you think I think they should be killed?
Saying "there didn't even need to be a trial" just makes you look like even more of a goon. Execution without trial was one of the things that the Coalition went to war to stop from happening. If the West wants to bring democracy and freedom to the Middle East, what better way to do it than by putting a former dictator on a fair and just trial? If the trial's got more holes in it than a mass orgy video, then what does that look like to the people whose country has been attacked?
