Ian Bremmer's Quick Take:

Hi everybody. Ian Bremmer here and a Quick Take, post-run, on a Sunday because the news does not wait for us to get back from our extended Thanksgiving weekend.

I want to talk about a new front in the Middle East war that has just opened up in Syria, a country that is far from stable and not really a country, really a patchwork of different controls in the best of times. But now we have active war fighting, a new front opening up with lots of territory being taken from Bashar al-Assad, his dictatorial regime from Syria Rebels, particularly a group called HTS, which is the most powerful of the military opposition groups in the country. They have swept, in a matter of hours, through the country, taking over Aleppo, the major city, and moving towards Hama. There is lots of humanitarian concern here. Not a surprise. You don't have hospitals functioning in Aleppo. You've got all sorts, thousands and thousands of people fleeing and nowhere obvious to go.
