UN Stabilization Mission in Haiti (2004-2017)
A Brazil-led UN force of roughly 13,000 at its peak deployed to Haiti after President Jean-Bertrand Aristide was ousted. It stayed 13 years and spent billions. In 2010, Nepalese peacekeepers introduced cholera, which killed thousands.
Gangs were pushed back in some areas but regrouped as the mission wound down.
The mission left a legacy of disease and distrust, and Haiti's gangs grew stronger after its exit.
It is the clearest precedent for what a large foreign force can and cannot do against Haitian gangs, and why residents are skeptical of another intervention.
