Turkey is nervous. Understandably.
But they won't do anything. They are rattling the sabre to tell Russia to stop where they are. They will act to defend themselves.
Turkey is a huge NATO stalwart, so IF they got involved in a defensive action against a Russian aggressive move THEN we're up the proverbial.
I can't imagine Russia doing that to turkey. The Turks are well armed and supported by the US. It would be utter stupidity.
