Purely looking at Russia’s lack of performance against the Ukraine I’d rather doubt that Russia would want a direct confrontation with Turkey unless, maybe, they could pinch-off a piece of territory and limit the confrontation.
But a lot of things would happen. Turkey would close the Bosporus to Russian traffic and the Russian expeditionary forces in Syria would likely end up in a Turkish prison camp for lack of re-supply.
The Russians need to have more babies. One of the reasons fecundity was always so important in the history of man is because that is the avenue from which real power grows.
Turkey is not done. Islamic nations will always be a threat to the rest of the world so long as they remain Islamic.
