An interesting analysis of the current state of play.

This time, the Jewish state proposed that Putin should give up his ties with Iran; in return, they promised to assist in general warming of Russo-American relations. Putin had a bigger counter-proposal: Let the US lift its Iran sanctions and withdraw its armed forces from Syria, and Russia will try to usher Iranian armed forces out of Syria, too. The ensuing negotiations around Iran-Syria deal would lead to recognition of the US and Israel interests in Syria, and further on it could lead to negotiations in other spheres.

This was a clear win-win proposal. Iran would emerge free of sanctions; Israel and the US would have their interests recognised in Syria; the much-needed dialogue between Russia and the US will get a jump-start.^[1]

Much more in the article. Highly recommended.
