What a fantastic Krauthammer column today (Kathryn linked to it earlier). He has an amazing ability to take something that has been endlessly discussed and through the sheer force of precision and logic, write something about it that comes as a sort of revelation. I especially liked the ending:

The principal issue, and measure of our success, is the shaping of disciplined and effective security forces. And that is why the political negotiations that have been dragging on are so critical. It is the political track that must secure leadership for both the defense and interior ministries that is nonsectarian and committed to a unitary force whose members do not answer to private warlords.
Civil wars are not eternal. This war will end not with an Appomattox instrument of surrender. It will end when a critical mass of Sunnis stops supporting the insurgency and throws its lot in with the new Iraq.
How does this happen? The stick is military — the increased cost in Sunni blood of continuing the fight. But the carrot is political — a place at the table for those Sunnis, some of whom are represented in parliament, who are prepared to abandon the insurgency for a share of power, a share of oil income, and a sense of security and dignity in the new Iraq.
This is doable. That is not to say it will be done. It is to say that those who have decided that because of “civil war” it cannot be done have been unreasonably panicked by something that has been with us all along.
