Two-and-a-half years after the U.S. pulled out of Iraq the country has crumbled into a bona-fide failed state, with Baghdad under siege by ISIS (jihadist militants from the Islamic State), who are having a run of Iraq, and some analysts now worry that ISIS will commit mass genocide against Iraq's Shi'a population if Baghdad falls. The war in Iraq started with Operation Shock and Awe but ended in a fizzle and, some would argue, in an epic exercise in human futility. 

The war in Iraq started with Operation Shock and Awe but ended with a fizzle, and, some would argue, as an epic exercise in human futility -- neither victory nor defeat was clear. Instead, with the exit of the last American troops, the final meaning of the war is muddled.  In its wake, the war left us with more questions than answers: Is this the victory we had longed for since Vietnam? Is this all we could muster after we invaded and occupied Iraq for nine years, supposedly to find weapons of mass destruction? Is Iraq now truly a free and sovereign nation, given the unending conflict between Shiite and Sunni Muslims there?
