As Russia and the United States are holding back-channel talks over de-escalation zones in southern Syria, there’s a larger question of whether the two countries might broker an ultimate peace deal for the Syrian civil war.
Officially, Moscow is relying on the de-escalation zones to be in effect for an indefinite term and considers them instrumental to settling the conflict. However, agreements on the “soft decentralization” of Syria reached in Astana, Kazakhstan, tend to prompt questions rather than give answers.
