sectors of the middle class, but most city inhabitants tended to view the guerrillas as one of Colombia's main problems. By the end of 2010, FARC-EP influence was significantly reduced in the regions where it had only carried out a recent military-focused expansion during the 1980s and 1990s, in part due to the failure to establish close social ties with local populations. Government offensives eradicated much of the visible guerrilla presence in northern and central Colombia as well as in Guainía, Vaupés and Amazonas, limiting FARC to clandestine operations. Similar military setbacks and retreats occurred even within its traditional strongholds, forcing the FARC to move towards the most remote areas, but there the guerrillas did appear to maintain popular support among the peasants that had developed organic links to the insurgency. FARC dissidents The FARC dissidents refers to a group formerly part of the Revolutionary Armed Forces of Colombia, who have refused to lay down their arms after the FARC-government peace treaty came into effect in 2016. The dissidents number some 1,200 armed combatants with an unknown number of civilian militia supporting them.

John 40 and their dissident 43rd Front moved into the Amazonas state of western Venezuela. Venezuela has served as the primary location for many FARC dissidents.

Peru issued a 60-day state of emergency in the Putumayo Province, an area bordering both Colombia and Ecuador. On the first day alone, more than 50 individuals were arrested in the operation, with the majority being Colombian nationals, while four cocaine labs were dismantled. International response The FARC were a violent non-state actor (VNSA) whose formal recognition as legitimate belligerent forces is disputed by some organizations.
