George W. Bush broke up Iraq when he ordered its invasion in 2003. The United States not only removed Saddam Hussein, it also smashed and later dissolved the institutions by which Iraq's Sunni Arab minority ruled the country: its army, its security services, and the Baath Party. With these institutions gone and irreplaceable, the basis of an Iraqi state has disappeared.

The End of Iraq describes the administration's strategic miscalculations behind the war as well as the blunders of the American occupation. There was the failure to understand the intensity of the ethnic and religious divisions in Iraq. This was followed by incoherent and inconsistent strategies for governing, the failure to spend money for reconstruction, the misguided effort to create a national army and police, and then the turning over of the country's management to Republican political loyalists rather than qualified professionals. As a matter of morality, Peter W. Galbraith writes, the Kurds of Iraq are no less entitled to independence than are Lithuanians, Croatians, or Palestinians. And if the country's majority Shiites want to run their own affairs, or even have their own state, on what democratic principle should they be denied?
