SYRIA UPDATE: The Assad regime is now in complete control of Damascus and the surrounding region. This means the strategic map of Syria has been greatly simplified.
The rebels are now down to four pockets of territory: Idlib province in the north, the Turkish occupation zone north of Aleppo, rural Daraa province in the south, and the area around the Tanf border crossing. Idlib and north Aleppo are both under the protection of Turkey, Tanf is under the protection of the US, and Daraa is probably under the protection of the US and/or Israel.
