I suppose a “popular uprising” is only on the tables when the United States supports it? Hopefully Haitians drive out the gangs and the foreign invaders who have drove the island to poverty since its inception. In all that time their spirits have not been broken.
Requesting and receiving foreign aid to stabilize Haiti is obviously better than having an island-wide turf war between the cutthroat gangs and the Bwa Kale vigilante squads who stomp people to death. There is little reason to believe that unorganized vigilante groups will be able to defeat the gangs nationwide if left to their own devices, occasional local successes aside. There also isn't any reason to believe that the rule of unorganized vigilante mobs would be good in the first place, even if it were a marginal improvement over current gangs. I know that a "people's revolution" of some form is an important part of your bizarre socialist eschatology, regardless of whether it takes the form of a descent into anarchy led by vigilante death squads. However, a vast majority of normal people think that would be a bad outcome. The best thing that could happen for Haiti is an intervention by it's neighbors to restore order, followed by a return to elected democratic government.
