The Gaitenistas, otherwise known as the Gulf Clan, are Colombia's largest and richest criminal armed group. They formed nearly 20 years ago but have gained considerable strength since Colombia's landmark 2016 peace agreement with the Leftist FARC guerrilla group. Today, The Gulf Clan controls much of Colombia's Atlantic coast and is a key player in drug trafficking and migrant smuggling. All the while, they use coercive tactics to control the population.

My guest today, Elizabeth Dickinson, is Senior Analyst for Colombia at the International Crisis Group and author of a recent report on this group. In our conversation, she explains how this group emerged to become such a potent force in Colombia today and why it is thus far upending President Gustavo Petro's efforts to secure a so-called Total Peace for all of Colombia.
