This is how I see it, and I have been saying since day one, we should align ourselves with the only sensible person in the game, and the one who knows what he is doing, - Vladimir Putin, who supports Assad because he (Assad) has refused to allow either of the two proposed pipelines to cross Syria, - one proposed from Qatar and the other from Iran, both would terminate in Turkey, from where the oil could continue onwards to Europe. The Americans want it because it will eclipse the Russian pipeline, damaging their economy even further, and thereby shaft Putin.
Putin's policy is simple, support Assad (at least for now) and attack anyone
not just ISIS, trying to remove him by force.
Joining forces with Putin would facilitate a speedier end to all conflict and give the best opportunity to bring the badly needed stability to the region.
