Opposition groups are deeply sceptical of the deal. Russia says it is willing to spare non-extremist opposition groups, but wants to know where they are. A joint US/Russian operation is central to determining future targets and Russia has said it will rein in the Syrian air force. They also doubt whether Russia can truly ground Assad’s air force, which has caused widespread, often indiscriminate, damage in civilian areas. Russia will have primary responsibility to ensure that the Syrian Air Force does not bomb opposition areas deemed to be “jihadi free”.
