Former Haitian dictator Jean-Claude "Baby Doc" Duvalier returned to Haiti on Sunday. According to the BBC, Duvalier—who was ousted in a 1986 popular revolt—is unlikely to actually regain power, but his presence could lead to "further instability" and hurt Haiti's chances at constitutional rule. Are there other ousted dictators who might be planning a come back?
Why, yes—but they're unlikely to succeed.
