It sounds like a lot of projects did complete successfully, but that this article only focuses in detail, on the failed one(s). One interesting point, is that Haiti was charging more than any other port in the region, for docking fees. People went elsewhere due to cost. The US may have stopped building the dock, if they discovered this highly counter-productive practice might continue. Speculation, but regardless, Haiti seems to be the problem, not those helping.
