Invisible US hand leading to war?: Turkey's Downing of a Russian Jet at the Turkish/Syrian Border an Act of Madness

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.

What makes the downing of the Russian jet, and the reported death of at least one of its two pilots (the other was reportedly captured alive by pro-turkish Turkmen fighters on the Syrian side of the Syria-Turkish border, and will presumably be returned to Russia) so dangerous is that as a member of NATO, supposedly a "mutual assistance" treaty that binds all members to come to the defense of one that is attacked, if Russia were to retaliate by downing a Turkish military plane, NATO countries including the US would be obligated to come to Turkey's defense.
