With all the fighting going on in Iraq now -- Shiite and Sunni alike -- those Iraqis who want a peaceful and democratic government need to have the guts to stand up and be counted, even if that means opposing their fellow countrymen. Everyone was hoping the transition would be mostly peaceful once Saddam was gone, but tyranny is apparently too entrenched in the populace and there are still plenty of people who'd rather stand alone atop a pile of skulls than work together to build a skyscraper.
America needs Iraq for military purposes, but if the Iraqis can't get their act together we may have to give up on reforming them politically. Our troops aren't leaving any time soon, but once we turn the government over to the natives they're going to have to fight these battles on their own. If the emerging Iraqi government wants to be respected, it has to demonstrate that it has the support of the population. That means the Iraqi people need to take responsibility for their country and not let it be torn apart by dead-enders.
Iraqis: if you want freedom and democracy, it's time to fight for it. We can't hand it to you on a silver platter. You've got to decide, and it looks like the time is now.
