Assad is down to 40,000 government troops. A year from now, Assad will either have joined his family in Russia, or he’ll wind up a wind chime, like Mussolini. And I wouldn’t put much stock in Iranian forces if I were him. Judging from their abysmal past performance against Iraq (last major war Iran ever fought), they’re paper tigers. So it’s going to be a 3-way dance between moderates, al-Nusra, and IS.
40,000 troops? Source please.
