Why has the US so often supported dictators over democratically elected governments?Because we feared that a democratically elected government would be less friendly to U.S. interests than the dictator. Often, the U.S. assumed that left-leaning opposition movements were Soviet fronts. Sometimes they were. Since the end of the Cold War, I think the balance has shifted favorably toward democracy.
If you do not agree that the US supports dictators over democracy- please provide examples.MacArthur did a pretty good job transitioning Japan from a dictatorship to a constitutional democracy.
Getting rid of a dictator can be costly. The U.S. has facilitated the peaceful removal of dictators with whom we'd previously been friendly -- once it became clear that they would soon be overthrown by their own people.
When I say the U.S. "facilitated their peaceful removal," I should clarify that the U.S. helped Ferdinand Marcos and Baby Doc Duvalier escape justice. Reagan thought the alternative would have been bloody civil war. The Philippines are still struggling with democracy, and Haiti so far has failed at it... But would they have been better off if Marcos or Duvalier had stuck it out to the bitter end?
[Replying to myself, adding this:] Finally, when listing the U.S.'s failures, remember there was another "imperialist" power involved in the Cold War:
Kim Jong Il, Ceausescu, Honecker, Zhivkov, Jaruzelski, Hungary 1956, Prague 1968; the list is long and lurid. Though often begun as popular movements, the communist regimes aligned with the Soviet Union were anything but democratic. Start an opposition political party, go to prison. Even Communist Party leaders who talked about liberalization (like allowing other political parties) might face Russian tanks arriving to "correct" them -- lest the country fall to the forces of capitalism. (This was the
Brezhnev Doctrine, as practiced in Prague in 1968.)
The U.S. generally supported dictators when the alternative looked like a permanent expansion of the Soviet sphere of influence. I say "permanent" because the Brezhnev Doctrine was intended to act as a ratchet. Once a nation had discovered the glories of socialism, it would not be allowed to renounce them.
The U.S., on the other hand, had no policy of opposing multi-party democracy in our allies. Our friend Marcos called an election in 1986 and lost. Did we send in the tanks? No, we just got him out of there. Pinochet's reign had a similar end. Are there any examples of the Soviet Union allowing one of its friendly dictators to be overthrown? (Before the whole thing collapsed, I mean.)
