So we see Maduro return and start a ruthless attack against the National Assembly, including the use of the fake Supreme Court justices to take down the opposition's veto proof majority.
I believe Maduro's disappearance from public view was caused by a visit to Cuba, to receive advice (orders?) from Raúl Castro and his Venezuela experts.
To figure out Maduro's behavior you have to think of him as being guided by Cuban military and intelligence personnel coordinated by Raul's son, Alejandro "el Tuerto". Alejandro is said to be somewhat of a psychopath, with average intelligence, and raised as a princeling. I've met these new generation communist oligarchs, they truly resemble 15th century nobility.

Unfortunately for Venezuelans, the information and suggestions Raúl is receiving from his people embedded in the Chavista regime are all filtered and shaped by Alejandro. My guess is that Raúl, Alejandro, and their nomenklatura feel they can have Maduro get away with anything. Why? Because Latin American, European, and other nations, and Obama, are being quite friendly towards their dictatorship in spite of its continuous human rights abuses.
