Haiti has never been known as a beacon of stability and tranquility. Most of its politicians are feckless, in league with criminals, or too consumed with trying to stay alive themselves. America not so long ago intervened on the island twice in ten years — the first time in 1994, when President Clinton’s threat of an invasion compelled the junta to reverse its coup three years earlier, and the second in 2004, when the Bush administration participated in an international stabilization force after Haiti’s President Jean-Bertrand Aristide resigned.
