Sunni tribal disagreements over the role of the Popular Mobilization Forces—which have so far prevented developing a broader security strategy against the Islamic State—might change in the aftermath of Ramadi.

If Iraqi parties cannot agree on a unified vision for the National Guard, options will remain limited for the U.S.-led coalition against the Islamic State.

As the Syrian crisis continues, Jabhat al Nusra and the Islamic State of Iraq may form a cross-border zone between Iraq and Syria that could threaten regional stability.
