From everything I have inferred and read, Russia (If not Putin, personally) has a degree of legitimate, democratic, support east of the Dnipro.

And yes.. One of the few outright broken promises Trump made was leaving Afghanistan.. I believe the reason is that Trump the layman saw it as common sense. As do most Americans.

When he won, the geopolitical significance of the war was impressed on him and he changed his position. So, yes. It is a legitimate flip/flop. Not something Trump is known for. But he did it here.

Frankly? China is romancing the Taliban goat fuckers outright, and have designs on a post US Afghanistan. That is probably the reason for his post election reevaluation/flip flop.
