In considering the terrifying but also sadly predictable news of a Russian fighter jet being downed by two Turkish fighters, let’s start with one almost certain assumption — an assumption that no doubt is also being made by the Russian government: Turkey’s action, using US-supplied F-16 planes, was taken with the full knowledge and advance support of the US. In fact, given Turkey’s vassal status as a member of US-dominated NATO, it could well be that Ankara was put up to this act of brinksmanship by the US.
