Realistically, Russia isn't going to enter into any sort of major conflict with the US over Assad / Syria. Putin isn't Kim Jong-Un... Syria simply isn't important enough to Russia to essentially commit national / global suicide, you don't blow your load over a political pawn. They won't be happy, though, and whilst not triggering it, it will edge further towards Cold War Mk.II.

Like I said before though there's very little point in talking about Obama / Clinton / Trump here. The President is not calling the shots on issues like these ffs, surely we're all old enough and wise enough to realise that? The fact that it's gone this way under Trump, after all of his rhetoric around Russian relations, is for me 100% proof of that. Puppets and talking heads, that's all we elect. They have sway over domestic political issues and the everyday running of the country... ... ... they are not the ones deciding when and where the world goes to war. Those people don't go on TV and twitter. You wouldn't know those people if you passed them in the street. And that's how they want it.
