To address your very good question about what happens if our strategy in Iraq succeeds, pushing ISIL at least temporarily but maybe in the medium term out of Iraqi territory, I'm a little skeptical about that. I think that other groups would spring up, as Professor Legrenzi has mentioned.
The plan in Syria, as much as there is a plan, and it's being debated in Washington now, is for the United States to intervene to degrade ISIL in Syrian territory to allow the Assad regime to try to consolidate some of their areas as a general containment measure. It is called now in Washington policy circles “uncoordinated deconfliction” between the United States and the Assad regime's forces: the United States is flying aircraft over Syrian territory; the Bashar al-Assad regime is not shooting at those aircraft.
The problem really is with the capacities of the Assad regime. If they were more inclusive and if they hadn't tried to shoot their way out of the country's largest uprising at the expense of 200,000-and-some killed and countless others imprisoned and tortured in such a bloody way, then I think they would have a hope of moving their forces into eastern Syria to defeat ISIL.
I don't think anyone expects them to do that. In fact, while they're advancing in the north, the Assad regime's forces are being pushed out of the south. That shows the complexity of this. It's there, in the wilds of eastern Syria, that the “train and equip” force that's supposed to be trained by the United States and its allies and its regional allies from four different sites in the region is supposed to take on ISIL at some indeterminate point in the future.
The problem, of course, is to motivate rebels who are in neighbouring countries to join that force and to fight ISIL first instead of fighting the Assad regime, which has been trying in one way, shape, or form to kill or strangle the opposition into submission. That's a circle that is very hard to square, or vice versa. Given what the United States is doing up until now—and I can only speak from an American standpoint—it will be insufficient to motivate local actors or local allies who back the opposition to fight ISIL and to displace its force in eastern Syria.
Also unpalatable is allowing the Assad regime to reconquer all of its territory, for two reasons. One is the nature of that fight and the lack of legitimacy of the Assad regime due to its actions over the last few years. But also, the Assad regime is in alliance with the Islamic Republic of Iran and its forces, which are in unprecedented numbers and level of influence inside of Syria as a result of supporting the Assad regime during the uprising. That threatens to destabilize the balance between Iranian-backed governments and forces and generally Sunni-backed governments or Sunni-based governments throughout the Middle East, and it makes this potentially much more explosive.
Like Professor Legrenzi, I wish I had a solution to propose to you. I think that in the end, diplomacy and military force in combination—and specially used in smart, intelligent ways based on a real political process—will be the thing that solves this for the United States, Canada, and its allies. But I'm afraid at the moment we simply don't see it and probably won't see it for some time.
