Sunni are the majority of the [Syria], 60 to 65 percent. They've been ruled by [Bashar] Assad, who represents a minority Alawite element, which is about 12, 13 percent. And because of the choices Assad made, it's very difficult to see how you resolve this without buy-in from the Sunni world.

If [Bashar] Assad himself could save this whole process by saying, "I will engage in a managed transition where we all work together to stabilize the government, save the institutions of government, and turn on ISIL and preserve Syria." That could happen. It all depends on one man, and Russia and Iran should not be so stubborn here that they tie this whole thing up simply because of one person.

America deserves a real discussion about real policy.

We have staring us in the face here an enormous opportunity to actually find a way forward to have peace and stability in Syria, to reconstitute it. It'll take years to do that. This will not be an easy fight even with concerted coordination with respect to ISIL. But it is far more doable with that kind of approach than otherwise.

I mean does Israel want a third Intifada?

No one is going to question my commitment to the defence of our nation. I don't know what it is these Republicans, who didn't serve in any war, have against those of us who are Democrats who did.

I think that all of the cyber attacks that are taking place, but particularly this - the Russian one, had a profound impact on the American system, on our political process, on our - it invaded the space of our election. The releasing on a regular basis of one party's stolen emails had an impact, and I think that other things also had an impact.
