The FARC is in total disarray, and they have the support of almost nobody in Colombia.
They can no longer be considered to be a guerilla group with any coherent political motivation, and they're not terrorists. They've just disintegrated to the level of becoming a criminal gang in the jungle and mountains who kidnap, extort, grow and sell drugs, etc. and do whatever else gangs do...
