Larison endorses an American presence Haiti:

There is a genuine American interest in at least restoring Haitian institutions to what they were before the earthquake.  Aside from the humanitarian concern for the population of Haiti, a failed state in the Caribbean would become a nexus of drug and human trafficking into the southern United States.  While failing states on the other side of the planet, such as Somalia and Yemen, pose very limited security threats to U.S. interests, the collapse of Haiti would swamp the southern U.S. with refugees at a time when state resources are stretched especially thin.  If Haiti is not made relatively stable and secure, Haiti’s neighbors, including the U.S., will bear the costs of that failure for decades.
