The question now is, will the Russians stand aside if the Turkish forces move further into Syria and attack the city of Manbij, where the Kurds are allied with US and French forces.

And will Erdogan's hostility to the Kurds lead to an armed clash among three NATO members.

"Those who cooperate with terrorists organizations [the YPG] will be targeted by Turkey," says Turkish Deputy Prime Minister Bekir Bozdag said in a pointed reference to France's support for the Kurds.

While the Saudis are doing their best to overthrow the Assad regime and fuel the extremists fighting the Russians, Riyadh is wooing Moscow to sign onto to a long-term OPEC agreement to control oil supplies.

But the war in Syria looks as if it is coming to some kind of resolution, and at this point Iran, Russia and Turkey seem to be the only actors who have a script that goes beyond lobbing cruise missiles at people.
