Troll-It's the same reason why democracy is struggling in Russia: they've lived under dictators for a long time, and it's a hard tradition to break. The idea of an occupier creating democracy seems kind of contradictory, because if it starts going wrong, you can either step in, destroying autonomy, or let them make their mistakes, destroying democracy. Either way, it's no good. Afghanistan may be worse, because it suffered from warlordism rather than a single tyrant. That doesn't mean it will be easy to set up the apparatus of democracy in Iraq, though.
