Absent in the discussion of the conflict brewing in the Andes over a Colombian military incursion into Ecuador to kill a guerrilla leader is the role of U.S. military in the conflict. It goes well beyond providing satellite intelligence on the location of guerrilla camps: the two countries have opposing responses to Washington’s attempt to militarize the hemisphere. Ecuador’s constituent assembly proposes prohibiting all foreign military presence, while Colombia seeks ever greater U.S. military hardware, intelligence and troops. The U.S. response has been quite undiplomatic.
