Apparently you haven't been following this very closely. Cubans are not permitted to engage in "self enrichment" and Castro does not work on a cash and carry basis. Castro expects the goods up front and gives his IOU. Castro has said he won't "trade" with the U.S. until he can get the deals "financed." Let me tell you Demigog, that means we, the consumers and the taxpayers (if the loans are backed by the govt.) will foot the bill.
Here's one man that is currying Castro's favor.
Venezuela · Chavez has insisted that oil sales continue to Cuba, despite an unpaid $97 million bill for past sales.--Source
If that is satisfactory with the companies who trade there then it is their choice. That can in no way be construed to be a burden on the American taxpayer. I am not obligated to bail out some company that agrees to those stipulations and then goes belly up. Sorry that you think this is so.
Ahh, I see. You are pro Embargo simply to prevent American companies from getting ripped off by Castro. Are you going to send them a bill for your consultative advice? I'm sure they'd be quite appreciative for saving them millions in bad business deals they wanted to undertake, lol.
