@hawkeye10,
I have said for months that the West's approach to Syria/ISIS was timid and unrealistic. Helping the "moderate opposition" to Assad and requesting Assad's departure, = the line followed by the US and France so far, is just wishful thinking. The secular opposition to Assad has all but vanished, meaning that, in spite of all the blood on his hands, Assad now represents the only significant secular force in Syria, with the possible exception of the Kurds.
Unlike others, Russia has put troops in Syria and is therefore able to act much more decisively than the US and France. And now Putin has finally understood that ISIS is well worth bombing too (their strikes so far had focussed on the immediate threat to the zone controlled by the Assad regime, i.e. Al Nusra, which indirectly helped ISIS grab new territory). This change is apparently because of the downing of the Russian plane in Sinai is now certain to be a terrorist attack, probably from ISIS.
This means that Russia has de facto become a key potential military ally for France. Hollande understands that. He flew to Moscow to meet with Putin today and they made deals. The French forces are going to coordinate with the Russian forces directly, share intel, etc. All this goes in the right direction.
Now Hollande needs to convince the US that working with Russia and the Assad regime is a necessity. It won't be easy but it's the only realistic way forward.
