This is laughable.
What will Cuba use for currency ?
That might be the only ‘good’ that comes out of this. The Castro’s will not be able to hide what they have done to their people anymore.
They pay in Cigars.
The US will loan Cuba the money to buy US equipment. When Cuba is unable to repay the loan, the US government will forgive it. (US taxpayers will pay US manufacturers for equipment that they give to Cuba).
If I were to sell anything in Cuba I would require a cash payment in dollars, gold or silver.
Or possibly trade for cigars.
