A very good article in today's Wall Street Journal regarding the trade embargo against Cuba and the myths surrounding it, us and them that have endured.
I've always felt the embargo a bad idea and it is continued to the benefit of only the few and is a political distraction. Removing the embargo would not reward the Castro regime, it would benefit Americans generally, which is what our government is supposed to be concerned with ("promote the general welfare").
A happy side effect is that it would benefit Cubans generally.
As I've written before, I don't have a hell of a lot of hope in the Obama administration's concept of economics, especially as it relates to his vision of "social justice" and Americans' liberty, but rescinding this ineffective anachronism would be a great way to dispel at least some criticism.
