All madmanduro cares about is himself.
Here is what we need to know about Venezuela:
1) There was an earthquake in Caracas a few years ago. There was footage that popped up online from there and other cities showing people pouring out of shaking buildings.
Not a single one of them looked like Jewish concentration camp photos of starvation. Not a single one. But US media for years manufactured empty grocery store pics and said people were fleeing the country because they had no food.
2) Maduro has won his elections. There is little doubt about 2015, though there was challenge and outcry. Then in 2018 there was another, scheduled for his advantage (much like ruling parties of the UK do) and amid louder outcry, he won that too. Note that most of the outcry is international, who have no say in the matter.
3) He, and before him Chavez, won those elections by pouring money into the poorest areas. The votes of peasants come to him. The pro capitalist people rage about this and say the poor can never progress because of this. But that’s where the majority vote comes from and if the majority opposes a policy, then that policy loses.
4) Venezuela’s oil is nearly all extra heavy and viscous. Orinoco heavy, named after a big river there. The latest talk of Chevron selling some oil (some of the small portion that is light) is almost certainly overhyped and meaningless, because Petrochina, Rosneft and Sinopec have poured money (as loans mostly) into Venezuela for oil field development and indeed, refineries that can process the very low API (viscous) oil. Chevron is not needed. This ongoing propaganda about spectacular technical advantages by US oil companies is just absurd. There is no expertise that cannot be bought, and generally speaking, Rosneft knows more than they do, regardless.
So there. Bottom line. Largely ignore all Venezuela stories from US media. These sanctions have been in place a long time now and all they have done is get Maduro recognized as president, after all.
