@fbaezer,
True enough. However Venezuela is facing growing economic problems - the currency is in steady decline; domestic production of goods is down, and imports are more necessary, and now far more expensive. More ominous is that Venezuela's oil production is down significantly - evidently the cronies with which Chavez populated the nationalized company don't run it as well as their predecessors. Between these factors and the likely growing subsidies and payoffs needed to sustain their political support, Chavez' successors (even if they don't fall out with one another) are likely to have a hard go of it in terms of the natiuonal economy.
For the (so far) ever-surviving Fidel this may mean the Venezuelan gravy train may soon stop running or merely deliver less to Cuba.
Venezula has for a very long time been unfortunate in its governments. Authoritarians of the right and the left and kleptocracies of both persuasions have prevented its intelligent development, even despite the potential of its enormous wealth of natural resources.
