The supporters of the war, from the Bush White House to Sen. John McCain, tout the surge as the magic solution. But the surge, which primarily deployed 30,000 troops in and around Baghdad, did little to thwart the sectarian violence. The decline in attacks began only when we bought off the Sunni Arabs. U.S. commanders in the bleak fall of 2006 had little choice. It was that or defeat. The steady rise in U.S. casualties, the massive car bombs that tore apart city squares in Baghdad and left hundreds dead, the brutal ethnic cleansing that was creating independent ethnic enclaves beyond our control throughout Iraq, the death squads that carried out mass executions and a central government that was as corrupt as it was impotent signaled catastrophic failure.

The United States cut a deal with its Sunni Arab enemies. It would pay the former insurgents. It would allow them to arm and form military units and give them control of their ethnic enclaves. The Sunni Arabs, in exchange, would halt attacks on U.S. troops. The Sunnis Arabs agreed.

The U.S. is currently spending hundreds of millions of dollars to pay the monthly salaries of some 600,000 armed fighters in the three rival ethnic camps in Iraq. These fighters-Shiite, Kurd and Sunni Arab-are not only antagonistic but deeply unreliable allies. The Sunni Arab militias have replaced central government officials, including police, and taken over local administration and security in the pockets of Iraq under their control. They have no loyalty outside of their own ethnic community. Once the money runs out, or once they feel strong enough to make a thrust for power, the civil war in Iraq will accelerate with deadly speed. The tactic of money-for-peace failed in Afghanistan. The U.S. doled out funds and weapons to tribal groups in Afghanistan to buy their loyalty, but when the payments and weapons shipments ceased, the tribal groups headed back into the embrace of the Taliban.
