I agree with just about everything you say except for this:
The ending of the embargo will allow Castro to raid our treasury as a result of giving Cuba access to the International Monetary Fund, and all the International Banks that are funded mainly by the U.S. taxpayers.I don't think this is necessarily true. The IMF will not be forced to lend them a cent. This could not possibly be a condition to the US lifting the Embargo. If a private business wants to undertake the risk in dealing with Castro, let them.
The farm lobby is looking to Cuba for business; they don't have to go back too far to figure out that this small country is not a good credit risk. Last year, it was reported that France canceled a grain shipment of $160 million due to Cuba's non-payment and that South Africa and Thailand stopped providing credits to the island. Eastern European governments have tried unsuccessfully to get payment on their Cuban debt. Cuba has one of the worst credit ratings in the world.
The farm lobby is the main recipient of corporate welfare. As far as the taxpayers foot the bill they will be happy to sell on credit to Castro.
It does not make economic sense to sell to somebody you know that will never pay back. ADM, the biggest recipient of corporate welfare, is at the forefront along with Castro in bilking billions of dollars of American taxpayers’ hard earned money
