We cant discount the probability that Raúl Castro is now tempted to continue to advocate a Stalinist system mixed with very small and weak private enterprise and joint ventures with foreign capitalists (a bit like China and Vietnam, but with limits on the growth of native private enterprise). This system would be run by a military caste topped by a Castro.
Raúl Castro and his grandson Raulito Castro, in line
to be the fourth Castro after his father Alejandro.
This is what he is doing in Cuba right now. And there's no sign he would ever let go of Venezuela. On the other hand he and his leadership cadre may consider Venezuela the key piece in a future mini empire. Given the central command and control, the dogmatic nationalism, the militarism, the use of brown shirts, leader worship, and other traits, this budding empire would be using a hybrid of Stalinism and fascism.
As for Ileana and Marco, they don't have the intellect to deal with Castros. Trump is a huge unknown, but the best outcome may be to see him shut down the efforts Obama made to keep both Castro and Maduro in power, and focus elsewhere.
Regarding Russia, I suggest you hit the books. The best option for the USA is to resolve the conflict it has with Russia, and get them on the USA side. I know this won't go over well with you since you are obviously following the "common wisdom" as sold by the USA neocons. The Russians are simply responding to what they see as USA aggression, which began with Clinton, continued with Bush, and escalated with Obama. Hilary Clinton is a neocon golem, she may have risked nuclear war ratcheting tension even higher.
And don't forget I'm not inventing this "crap". I worked and lived in Russia for almost a decade before I moved to Venezuela, and I know how the Russians think, why Putin is in power, and what he expects from the USA. I think Flynn does too, and I'm 87 % in tune with him.
