Meh. Have we achieved anything with the Cuban embargo? Not really. They're not going to change, so what's the purpose?
Sure, you can argue that if the embargo is lifted, we'll be indirectly or even directly funding a communist regime that violates human rights. But if that's truly the concern, then why are half of my electronics from China?
I know, I know...we're financially dependent on China for a variety of reasons, but if we're going to take financial stability over the moral high ground, then you have to look at the fact that it is estimated that the Cuban embargo costs us billions of dollars a year in lost sales from exporting, and that additional jobs related to agricultural exports could be created if the embargo were lifted. I don't know what the costs are of enforcing the embargo, but that should also be considered.
I'm not gung ho about lifting the embargo, but I don't see a huge deal if it were lifted. There will likely be positives and negatives to it, but the whole concept of keeping it simply because Cuba is "evil" doesn't really jive with our relations with other "evil" countries.
