The Turks shot down a Russian military jet somewhere along the Turkey-Syria border. One pilot was reported killed after ejecting, likely by ground fire, the other was rescued. Now Russia and Turkey are arguing about whether the jet was or was not in Turkish airspace.
It becomes ever more clear that Erdogan's Turkey is abetting an ISIS victory in Syria. They see ISIS crushing both the Assad government and the Kurdish rebels.
Largely Sunni Turkey roots for Sunni ISIS, against Assad's Alawites and his Shia allies - the Iranians and their local Hezbollah proxy from Lebanon. Plus it has been clear for over a decade that Turkey would go to war to prevent the establishment of a Kurdish state anywhere near their borders.
Turkey is a NATO member, if attacked by Russia they could demand NATO support them in fighting off Putin. Defending a Turkey that supports ISIS would be extremely unpalatable to other NATO nation members.
There is every chance NATO would not comply, if it appears Turkey instigated the fight. At that point, the whole NATO schemata is called into question, something Putin would flatly love. It gives him a motive to attack Turkey, perhaps shoot down a couple of their planes, trying to goad them into jumping in with both feet. Watch this space.
