Dan Drezner is mildly in favor of lifting the trade embargo on Cuba. While I think he slightly overestimates how totalitarian the Cuban regime is—I think it’s done a very effective job of brainwashing much of its populace, and it is almost as brutally oppressive toward political dissidents as the North Korean (DPRK) regime, but I don’t think it has as effective a repression apparatus as North Korea has or some of the old Soviet client states (most notably Romania) had, and by all accounts there’s a degree of economic freedom at the margins absent in the DPRK—I agree that simply removing the embargo won’t lead to miraculous political change. However, it will deprive Castro and his Hollywood apologists of their one legitimate grievance against the United States government—and, for that reason alone, the sanctions regime should be removed.
