Liberal Thomas Friedman wakes up to the obvious - American policy in Iraq was necessary to prevent a worse situation:
What to do? I continue to believe that the best way to understand the real options — and they are grim — is by studying Iraq, which, like Syria, is made up largely of Sunnis, Shiites, Christians and Kurds. Why didn’t Iraq explode outward like Syria after Saddam was removed? The answer: America.
For better and for worse, the United States in Iraq performed the geopolitical equivalent of falling on a grenade — that we triggered ourselves. That is, we pulled the pin; we pulled out Saddam; we set off a huge explosion in the form of a Shiite-Sunni contest for power. Thousands of Iraqis were killed along with more than 4,700 American troops, but the presence of those U.S. troops in and along Iraq’s borders prevented the violence from spreading. Our invasion both triggered the civil war in Iraq and contained it at the same time. After that Sunni-Shiite civil war burned itself out, we brokered a fragile, imperfect power-sharing deal between Iraqi Shiites, Sunnis and Kurds. Then we got out. It is not at all clear that their deal will survive our departure.
Still, the lesson is that if you’re trying to topple one of these iron-fisted, multisectarian regimes, it really helps to have an outside power that can contain the explosions and mediate a new order. There is too little trust in these societies for them to do it on their own. Syria’s civil war, though, was triggered by predominantly Sunni rebels trying to oust President Bashar al-Assad and his minority Alawite-Shiite regime. There is no outside power willing to fall on the Syrian grenade and midwife a new order. So the fire there rages uncontrolled; refugees are now spilling out, and the Shiite-Sunni venom unleashed by the Syrian conflict is straining relations between these same communities in Iraq, Bahrain, Lebanon, Saudi Arabia, Turkey and Kuwait.
