Remember Iraq?

The Washington Post has an excellent editorial summarizing Iraq's constitutional conundrum. It does not appear that the constitution will be the panacea that some folks had thought it would be. It simply boils down to the same old problem that concerned me even before we invaded: how do you come up with democratic government in Iraq that will not dissolve into violent factionalism between the Kurds, Shiites, and Sunnis? I wasn't sure it was possible then, and nothing I'm seeing now is convincing me otherwise. It just isn't clear to me that the population in Iraq is homogeneous enough or has a strong enough sense of nationalism to be able to support a democratic federal government.
