While Aristide was not perfect, however much better than the US supported brutal/murdering dictator "President for life" Duvalier. Assuming all the above allegations to be true, they are still nothing compared to killing 30,000 of your own citizens.

Also, the CIA have admitted to have been involved in the distribution of Drugs, so bare that in mind when criticising leaders/countries.
