If you listen to those opposing normal diplomatic relations with Cuba, you learn that we should not do so until Cuba moves toward democracy.
With that rationale, we should be ending diplomatic relations with many countries, because no matter what our ideals and aspirations, the world still includes some fairly undemocratic nations.
Such as China. We have had full diplomatic relations with the People’s Republic of China since 1979, a period that includes both Republican and Democratic Presidents and Congresses. There is no way to characterize China as a democratic, democratic-leaning, democratic-seeking nation. So we should immediately recall our latest ambassador, former Sen. Max Baucus, and immediately close our embassy in Beijing.
Of course, that doesn’t make sense. As nothing has made sense in our relations with Cuba, even before Fidel Castro overthrew the Batista regime in 1959. The U.S. supported Batista and opposed Communism in the hemisphere. Commercial interests, legal and illegal, made money. Once Castro was in power, and refugees of substantial and modest means resettled in the U.S., it was thought that isolating Cuba would make it come around to right thinking and lucrative democracy. That didn’t work, and neither did the one attempt at forcing the issue, the debacle of the Bay of Pigs invasion.
If we had given Cuba the benefit of the doubt that we have given other non-democracies, not to mention the money we have invested in those nations, some good might have come of it, with little downside. But as with many issues, politics in the form of financial support, or the threat of withholding it, distorts what may be for the best.
Which is why, with Obama moving to normalize Cuban relations, you won’t hear anybody calling for the closing of the Beijing embassy, but lots of grandstanding and bluster about how a Cuban ambassador will mean the end of the world.
