I’m sure that given just a few more years the Cuba embargo will work........
Cuba can buy anything from US, although much of the food and medicine are donated, in fact they buy anything and everything they need, even those that are prohibited, Cuba buys them through third countries. The problem is that Cuba buys but doesnt pay to its creditors. That is why it is so important the embargo; Cuba must pay in advance for the products bought from U.S . Not on credit otherwise it is the American taxpayers the ones who would end paying for the merchandise sold to Cuba.
