Last week, the extremist militant Sunni group — Islamic State of Iraq and Syria (ISIS), along with other Sunni militias and former Baathist party members, seized control of large parts of Iraq, including Mosul, the nation's second largest city. In many places, the Iraqi army barely put up a flight. Soldiers dropped their weapons and fled, whether because of fear, incompetence, or internal sabotage. Hundreds of thousands of Iraqis have become internally displaced after fleeing the fighting or the potential for potential Iraqi air strikes. As ISIS and the other groups continued to fight their way to Baghdad, gruesome videos of brutal executions began to surface. Iraqi army units stationed near Baghdad, as well as Shiite militias, have pledged to not give up so easily.
