Will Iraq Return to Full-Blown Sectarian Civil War? Jamie Dettmer The expulsion of U.S. troops from Iraq, which Iran has long wanted and the Iraqi Parliament is now demanding, may rebound on Tehran, say some analysts, especially if the Iranians seek to amplify the political turmoil in Iraq with the aim of pushing U.S. forces out of that country this year. "The danger is a return to civil war," according to Niall Ferguson, an analyst at the Hoover Institution, a U.S.-based research group. Amid heightened sectarian tensions, a Sunni-Shi'ite conflict is one of the possible outcomes of the killing of top Iranian general Qassem Soleimani in a U.S. drone strike. Soleimani was Iran's master fixer in the Middle East and commander of the country's elite Quds Force, the unconventional warfare and military intelligence wing of Iran's Islamic Revolutionary Guard Corps. .
