Abu Muhammad al-Golani is an Islamist fanatic, a head-chopper (although only in moderation), and the leader of the Nusra Front, an al-Qaida affiliate that is classified by the United States as “terrorist.” He spent almost a decade killing American occupation troops and Shiite civilians in Iraq as a loyal member of the Sunni extremist organization that is now called Islamic State before going home to Syria in 2011.

He was sent home to create a Syrian clone of what was then called “Islamic State in Iraq,” on the orders of Abu Bakr al-Baghdadi, the leader of Islamic State and now the self-proclaimed “Caliph” of all the Muslims. Golani named the Syrian branch the Nusra Front, and it did so well that he broke with Islamic State and went out on his own in 2013.

There was a three-month turf war between Islamic State and the Nusra Front in Syria in early 2014 that killed an estimated 3,000 jihadis. Islamic State won it and now controls most of eastern Syria (and all of western Iraq). Golani managed to hang on to northwestern Syria, where the Nusra Front and another extreme Islamist organization, Ahrar al-Sham, now completely dominate a rebel alliance that also includes several smaller “moderate” outfits.

So you would not expect Golani to favor a peace deal that left the brutal Assad regime, secular in form but Shiite-dominated, in power in Damascus. And indeed he does not: In a rare interview recently, he condemned the peace deal being cooked up by the U.S. and Russia as “unacceptable.” It was, he said, a plot to merge more moderate rebel fighters with Assad’s forces in order to fight extremist groups such as his own and the Islamic State.

Golani was right to be suspicious, and yet he may go along with the deal in the end, because it isn’t really a permanent peace settlement that is being discussed. It’s actually just a ceasefire that will leave all the players in Syria in control of the territory they now hold — except for the Islamic State, which they can then all concentrate on destroying.

You can’t admit that that’s what you are doing, of course, so you talk in terms of a peace settlement. That’s what Russian Foreign Minister Sergei Lavrov and U.S. Foreign Secretary John Kerry were doing in Moscow Tuesday, and the result is a United Nations Security Council resolution endorsing the Syrian peace process passed Friday.

The current round of “peace talks” began in Vienna Oct. 23, with no Syrians present, just Russia, the U.S., Turkey and Saudi Arabia. It subsequently expanded to include about 20 countries, and the organizers are now deciding which Syrians can attend the next round of talks, probably early in the new year.

On one side, obviously, will be the the representatives of the Assad regime. On the other side will be some of the leaders of the armed opposition, but not all of them. Islamic State won’t be there, of course, and at the moment the Nusra Front says it won’t be either. Since those are the two most powerful groups fighting the Assad regime, what’s the point of talks?

But the Nusra Front’s close ally, Ahrar al-Sham, did show up at last week’s meeting in Riyadh in Saudi Arabia where decisions were being made on which groups could attend the peace talks. At one point, it walked out — and then, after some further thought, it added its signature to the joint declaration.

The Islamists of the Nusra Front and Ahrar al-Sham are clearly in two minds about a ceasefire (disguised as a peace agreement). On one hand, it would leave the Assad regime in power. On the other, it would give them time to consolidate their control over the territory they now hold, and maybe to eliminate their most dangerous rival, the Islamic State. So in the end, they may go along with the idea.

It wouldn’t be perfect, and it wouldn’t necessarily be permanent either. But it would stop most of the killing, it would at least contain if not eliminate the Islamic State, and it might even let some of the refugees go home. It’s basically a Russian initiative, but Moscow is wisely letting the U.S. take the lead now. If anybody has a better idea, please let us know.
