BAGHDAD -- First Lt. Justin John, 6-foot-4 and built like a linebacker, plopped down on a sofa in front of Ibrahim Suleiman al-Zoubaidi, one of the leaders of the mainly Sunni armed groups that have helped the U.S. military quell violence in Iraq since last year. Zoubaidi, a small man armed with a revolver, had one thing on his mind: This week officials of Iraq's Shiite-led government will assume authority over the groups, which have been backed by the United States.
"They will kill us," Zoubaidi declared. "One by one."
Across Baghdad, leaders of the groups speak about the transition in similarly apocalyptic terms. Some have left Baghdad, saying they fear that the Iraqi government will conduct mass arrests after the handover. Others are obtaining passports and say they will flee to Syria.
