The covert campaign in Colombia

This is an in-depth, fascinating article about the US's clandestine role in Colombia's assault on the FARC leadership over the past decade or so.  It gives a general review of the course of the Colombian internal conflict in this century, and gives new information on the US's participation in the conflict.  I guess the FARC always assumed/knew that the US was involved in the precision airstrikes that have decimated their hierarchy, but this article confirms that involvement.  I hope it doesn't derail the ongoing peace talks in Havana.
