Can Abadi save Iraq?

Haider Al-Abadi, the Prime Minister of Iraq since 2014, had an enormous responsibility on his shoulders: destroy ISIS from Iraq. That task has been mostly completed, except in more sparse regions like Tal Afar, Hawija and Al-Qaim.

Yet still there is a risk of ISIS returning to Iraq. One only has to look back at 2006 to know that ISIS once existed in the Baghdad, Diyala and Anbar provinces under the name Islamic State of Iraq, previously known as Al-Qaeda in Iraq.

Sound familiar?

ISIS has existed in Iraq, with different names, since the beginning of the Iraq War. It is a symptom of a persistent problem: Sunni Arabs felt under represented, and Shi'ite Arabs did not care for their Sunni Arab brothers. This fueled a toxic combination: one of Sunni Arab frustration but also of Shi'ite Arab indifference. This is why the Iraqi Army, largely Shi'ite, fled when ISIS invaded Sunni Arab Iraq in 2014.

But Haider Al-Abadi is not Nouri Al-Maliki. Nouri Al-Maliki was the previous Prime Minister of Iraq who fuelled sectarianism in the country deliberately, which can be seen from his rhetoric and policies. Abadi, however, is different: he is seeking to bring the Sunni and Shi'ite Arab Iraqis together as one country and people.

Can Abadi stem the tide of an ISIS return? That will largely depend on how he handles the Sunni-Shi'ite Arab relations post-ISIS. His recent visit to Saudi Arabia, a Sunni Arab powerhouse, the first country on his Middle-East tour, is a good start. But his greatest challenge in the short-term will be negotiating a settlement with the Kurds in Kirkuk and Erbil - should the Kurds break away from Iraq, Abadi will be faced with an even bigger challenge: how to maintain credibility after losing Iraqi Kurdistan.

Another concern is the increased instability in the Gulf. ISIS may indeed rear its ugly head in Saudi Arabia, Kuwait, Bahrain and UAE, and, as it did from Syria, may seek to invade Iraq from the south. But Iraq will only be susceptible to another ISIS invasion if Abadi cannot unite Sunni and Shi'ite Iraqis together under him.

Abadi's task is an enormous one. Should he succeed, Iraq's unimaginable suffering would lessen at last.
