On Tuesday, the UN Security Council publicly discusses Syria for the first time since the fall of Bashar al-Assad. Eyes will be on the Syrian delegation, appointed by the Assad government but thus far kept in post, and the old regime’s ally, Russia. The Kremlin’s diplomats are said to be co-operative; Russian media now call Hayat Tahrir al-Sham, the dominant rebel force, an “armed” rather than a ‘terrorist’ group. Nevertheless, America is wary of letting Russia use its veto power to shape the transition to its liking.
