What idiot told you majority means all? 55/45 is a majority, dumbass.
I apologize. Nobody said majority means 'all' -- in particular, not me. But I admit I misspoke about Venezuela "handing over 65 million barrels of oil." Nor is any of it apparently at no cost.
Nevertheless, Donald Trump's own media post was confusing. He said his subordinates “secured majority U.S. control of more than 65 BILLION BARRELS of proven Oil Reserves in Venezuela, at no cost to the American Taxpayer.”
The text of the agreement is still not released, but what we know is that the USA gets 55% of the effective output of a new Venezuelan company, with an ownership stake and an option to buy oil at cost, rather than the full market price. A bit more detail here.
So Venezuelan oil will certainly be cheap, but there is still the task of rebuilding Venezuela's oil industry, and that will not be cheap or quick to do.
