If you think the execution of Saddam was in accordance with the rule of law, you're delusional. The US government disagrees with you. The Iraqi government disagrees with you, and has already arrested the guy who shot the video. I suspect that the best day of the rest of his life will be worse than the worst day of the rest of my life.
The whole damn point is that we should be bringing them up to our level, not lowering ourselves to theirs. Otherwise, why bother? Did three thousand Americans die to bring Iraq from one form of barbarity to another form of barbarity?
Of course not. If we don't believe that Iraqi Arabs are capable of democratic self-governance, we're wasting time, treasure and blood on a lost cause. If there can be no democratic Iraq, we should just punch out and stop being targets.
I believe that Iraq (Babylon) and Iran (Persia) can find their way out of recent craziness and back to their noble traditions. If not, well, I'll brace for when all Hell breaks loose, and we have to choose between being present and killed or absent and irrelevant.
