Frankly, I don't know that sanctions ever work. They haven't against Castro, certainly.
But what's the argument for lifting them? If you could buy cell phones and computers and Nike sneakers and good clothing and Persian rugs and Gatorade and God knows what else, the economic advantage to ending the embargo might make sense.
But what could you buy from Cuba? Sugar, which we seem to be able to get anyway at ridiculously cheap prices - under 20 cents a pound last time I checked, so who needs Castro's? And cigars, which, face it, are not a significant portion of our trade.
So really, the economic harm to the U.S. from the sanctions is insignificant.
So why should we lift them? We'd only be helping to prop up and further enrich a murdering dictator, for little benefit to ourselves. Where is the outrage from the bien-pensants here? They get their britches in such a twist because we support other dictators, then when we say that at least we won't support this one, they get their britches in a twist over that. How do you get on the bien-pensants list of approved dictators? Musharref would like to know.
