Next Tuesday is the official deadline for US combat troops to withdraw from Iraq's towns and cities. At Iraq's request, the American presence already is being pulled back. Prime Minister Nuri al-Maliki calls the withdrawal a "great victory" for the Iraqi people. But many Iraqi people have other ideas. A new wave of bombings has now killed more than 200 people in the past two days. Has sectarian violence already resumed between Shiites and Sunnis? Will the Kurds rebel against a central government dominated by Arabs? Will Iran intervene, in part to divert attention away from its own problems?
