With the help of Russia and Hezbollah, Assad’s army liberated the ancient city of Palmyra from Islamic State. Palmyra is a UNESCO world heritage site and over the course of the last nine or so months, ISIS has obliterated a number of priceless artifacts on the grounds that they are monuments to paganism.
Needless to say, it’s better that Assad control the city than ISIS. Even the US State Dept. was forced to (begrudgingly) admit as much.
But Washington’s reluctance to celebrate the liberation of Palmyra reflects growing concerns that Assad, Hezbollah, and other Iran-backed Shiite militias are now poised to march on Deir ez-Zor – and then on Raqqa.
