you still haven't explained what the alliance with Russia would consist of - yes, I have. It was in answer to your earlier question: who would be Russia's allies in Syria? The allies would be the US, EU and other Western countries. Russia would bomb the terrorists in Syria; the West would bomb terrorists in Iraq.
Russia intervene in Syria with a bombing campaign against the western-backed rebels - but the West, being allies of Russia, would abandon those rebels. The West has no legal right to be in Syria.
let's stand aside and let Assad wipe out the last pro-western anti-Islamic forces - I said that some members of this extremely tiny minority can be persuaded to lay down their arms and accept Assad's rule. Those that insist on prolonging the war and causing instability by carrying on fighting can be wiped out with the depraved Islamists.
putins response: trollollollolol - that would also be my response.
