I think it's important to remember the tensions between Turkey and Russia predate this jet shoot down by some time. I mean, Russia's long been Bashar al-Assad's strongest backer.
We are seeing reports that NATO's sending early warning radar planes and German military personnel to Turkey. That might reduce the chances of another incident like this jet shoot down. And obviously both NATO and the U.S. are pressing their ally Turkey to urgently deescalate the situation.
Turkey's NATO membership is one thing that is forestalling the worst-case scenario - open conflict between Russia and Turkey - because neither Moscow nor the West wants a Russian NATO conflict to erupt.
