There is indeed a US windfall phenomenon to regain control of Venezuela but the conditions for that to happen are there
Venezuela is too dependent on oil exports, a barrel at 50USD is not enough for the needs of Venezuela.
Venezuela depends too much on the US economically who are its first customer and its first supplier. Especially are first customer in the oil.

Hugo Chávez certainly did a lot for the people but forgot that to last it was also necessary to develop the economy, to make Venezuela less dependent on the outside world.

He did not do it for ideological questions by not putting in place laws favorable to entrepreneurship (personally I only know capitalist entrepreneurs)

The only hope is that finally the barrel goes up but even that will not solve the problem because the US now import much less oil from the Gulf or Venzuela because of the arrival of shale gas on the shelves. The US is practically self-sufficient and ironic is when the price of oil is low that shale gas becomes less profitable. If oil went up the US would mechanically reduce the import of oil to buy instead its domestic production.

Conclusion: Bad revolutionary planning. For now it does not work.
