NY TIMES
Insurgent commanders say that since Russia began air attacks in support of the Syrian government, they are receiving for the first time bountiful supplies of powerful American-made antitank missiles.
With the enhanced insurgent firepower and with Russia steadily raising the number of airstrikes against the government’s opponents, the Syrian conflict is edging closer to an all-out proxy war between the United States and Russia.
The increased levels of support have raised morale on both sides of the conflict, broadening war aims and hardening political positions, making a diplomatic settlement all the more unlikely.
