It seems clear that pro-government forces in Iraq are preparing to retake Mosul, Iraq’s second largest city. The Islamic State (ISIS), a Sunni extremist group, captured Mosul following a series of assaults in June 2014, an offensive that ultimately resulted in an embarrassing collapse of the Iraqi Army in northern Iraq. Since then, the Iraqi government has made the recapture of Mosul a key domestic goal in its fight to reclaim its territory and reassert its control over a restive minority Sunni population. Prior to the events of 2014, the Sunnis were agitating for greater regional autonomy, akin to the political status of the Iraqi Kurdistan Regional Government (KRG), and strongly against the Shiite-dominated central government.
Mosul lies at a strategic juncture between a number of groups, including the Turks, Kurds, Arab Sunnis and Persian Shiites. It is also lies in close proximity to several states and territories, including Iraq, Iran, Turkey, Syria, and the autonomous northern KRG. Which party controls this city is a significant determinant for all of these regional powers when considering their border security and foreign policy.
