The U.S. isn’t the only outside power involved in this conflict; far from it. A tangled and intricate web of countries is now increasingly involved. The Syrian rebels have been supplied with arms from Qatar, Turkey, and Saudi Arabia, often with the help of CIA operatives. Meanwhile, Russia announced its intention to sell its Syrian ally S-300 anti-aircraft missiles. That, in turn, drew the ire of the Israelis, who fear that those missiles could fall into the hands of Hezbollah, which is fighting on the side of the government.
