Putting aside your scurrilous and baseless attacks on my stainless character, you have a very tenuous grasp of geopolitics.
First, Russia was never leaving Tartus. Much of Russia's investment in Syria, along with a serious and legitimate desire to be a regional power broker, is centered on that installation.
Second, Russia isn't getting what it wants, we are. Putin tried to have his "mission accomplished" moment in Syria about two year again December, 2017:
https://www.reuters.com/article/us-mide ... SKBN1E50X1 It's working out, predictably, about as well as GWB's victory lap in Iraq. We didn't leave fighting in Iraq for many more years, and the Russians have bought themselves a similar project trying to put humpty dumpty back together again. Now they say that they will intervene even further to stop fighting between Syria and Turkey...lol good luck with that.
Finally, none of this speaks to some special genius of Trump, but in a way, that's the point. You can't be dragged further into a conflict if you're not there in the first place, and we never had a cohesive, meaningful strategy based on valid geopolitical aims. We blundered into this shit with moronic neo-liberal platitudes about spreading democracy and opposing tyranny and an inflated vision of ourselves as the world police. Trump, with his self serving junior high grasp of life, is right: we shouldn't be there, we have no reason to be there, and we should get out. There's nothing in it for us. It is precisely listening to the foreign policy establishment that has led us into two decades of continuous fighting in the ME, and it has gotten us nothing. Do you think the Iraqis or Afghani's or Libyans love us for our interventions?
