Plans to liberate Mosul, a key stronghold of the Islamic State (IS), are gaining momentum in Iraq. Many Sunni Arabs who initially tolerated IS are now seeking revenge for its killing families and friends and confiscating their property. Sunni Arab forces are being organized, trained and armed in Erbil to counter IS with the cooperation of the Iraqi federal government, the Kurdistan Regional Government (KRG), the Mosul provincial council and the US-led coalition. Still, this effort is complicated by intra-Sunni Arab disputes over leadership and relations with Baghdad and the Kurds, as well as Kurdish disinterest in liberating and protecting Sunni Arab territories. These disputes highlight the challenges of not only degrading IS, but stabilizing Mosul in a highly fragmented Iraqi state.

Most local populations brutalized by IS want to liberate Mosul. Those who have thus far joined the Sunni Arab force are mainly displaced Mosulawis residing in the Kurdistan Region and organized by Atheel al-Nujaifi, Ninevah province governor “in exile.” Nujaifi not only wants to re-secure his political position and Mosul city, but establish and lead a larger Sunni Arab region like the Kurdistan Region. Nujaifi has advanced his political agenda with backing from Turkey, Saudi Arabia, the Iraqi Ministry of Defense and Iraqi Kurdistan President Massoud Barzani.

The problem is that Nujaifi has lost significant local support from Mosulawis and is not representative of the powerful Sunni Arab streets. Arab members of the Nahda (Renaissance) bloc, which controls about 20 of the 39 seats on the Mosul provincial council, have called for Nujaifi’s dismissal. The Nahda bloc also boycotted the meeting held last month in Baghdad with Iraqi Prime Minister Haider al-Abadi because of Nujaifi’s presence. Many hold Nujaifi responsible for "losing Mosul" and supposedly maintaining relations with IS — an issue lately debated on the influential national al-Baghdadia television program. The Iraqi general public is also demanding that Nujaifi’s brother, current Iraqi Vice President Osama al-Nujaifi and former Iraqi Prime Minister Nouri al-Maliki be taken to court because they "gave half of Iraq to IS."

Ironically, the only real support for Nujaifi on the Mosul council is from the Kurds, largely from Barzani’s Kurdistan Democratic Party. Barzani may realize that Nujaifi is politically weak and a better Sunni Arab official to negotiate Kurdish interests and the disputed territories. Similarly, the Kurds have 16 seats on the Mosul council and the Kurdish vote can potentially help Nujaifi retain the governorship. Ascertaining Nujaifi’s position could also benefit Barzani and Turkish Prime Minister Recep Tayyip Erdogan by facilitating joint commercial and energy development projects between Mosul, the Kurdistan Region and Ankara.
