Analysis: Iraq exit via Iran?

This snippet isn't enough to make the author's case, but read it all:

The Iraq war, civil or not, is costing $226 million a day -- or $8 billion a month, $76 billion a year. Hard to figure out what to call it when Iraqis are killing Iraqis by the score every day and when the U.S. has been fighting and dying there longer than its involvement in World War II. Iraq also has a civil war within a civil war -- insurgency interspersed by sectarian warfare against a Shiite-led government.

There are 23 armed militias in Baghdad alone. Each government minister and scores of tribal leaders have their own self-defense force. Some 2 million Iraqis have fled their homes, the equivalent of 30 million Americans displaced by war. Jordan, a small country of 5 million now has to cope with 1.5 million Iraqis who have strained essential services to the breaking point and driven real estate and rentals beyond the reach of even well-to-do Jordanians.

The costly effort in blood and treasure to foster democracy in Iraq is clearly beyond our reach. Henry Kissinger, the chief mandarin of geopoliticians, who negotiated the 1973 agreements that ended the Vietnam War, says Iraq is unwinnable. If by victory, he explained, we mean a viable democratic Iraqi state, able to sustain itself, forget it because it can't be done. A far cry from "failure is not an option."
