For over 50 years the Colombian government and the Revolutionary Armed Forces of Colombia (FARC) fought a brutal civil war that displaced millions and killed 200,000, mostly civilians. Finally a peace agreement was finalized in November 2016.
But not everyone welcomed peace. Right-wing extremists opposed the negotiations, and the agreement itself. Those extremists happen to be former president Alvaro Uribe and current President Iván Duque.
The U.S. said that we supported peace, but we lied.

Colombia’s El Espectador newspaper on November 8 published Edinson Bolaños’s report that outlines a U.S. plot aimed at immobilizing FARC leaders. His information came from 24,000 recordings of wiretapped telephone calls occurring in 2017.

In most of the conversations, Marlon Marín speaks with two U.S. Drug Enforcement Agency (DEA) agents posing as representatives of Mexico’s Sinaloa drug cartel. They talked about 10 tons of cocaine that agents of Marín, posing as FARC members, eventually sold to the cartel for $5 million. The Office of the Attorney General supplied the cocaine used in the deal.

According to Bolaños, the conversations introduced alleged drug-trafficking accomplices by mentioning their names or faking their voices on the calls. One was Jesús Santrich, spokesperson for the FARC peace negotiators in Havana. Another was Iván Márquez, who headed the FARC’s negotiating team and is Marlon Marín’s uncle.
...Police agents arrested Santrich on April 9, 2018. Charged with conspiracy to export cocaine to the United States, Santrich faced extradition and trial before the U.S. District Court – Southern District of New York. Colombian authorities also arrested Marlon Marín and quickly flew him to the United States as a witness against Santrich.

Santrich spent 13 months in prison, but was eventually released when the case collapsed.
When the Colombian government decided to pursue the case anyway, Santrich, Iván Márquez, and other former FARC insurgents returned to armed conflict.
The government's war on FARC had never stopped. 242 former rebels plus 1,055 social and community activists have been murdered since the peace deal.

The people of Colombia support the peace process. Last year they staged absolutely massive protest, and three general strikes, plus another general strike last month.
The strike committee's list of demands included full compliance with the 2016 peace deal, and a repeal of neoliberalism.
Ironically, the real drug lords are the presidents.

Two months later, the Supreme Court’s fraud and bribery trial kicked off against Duque’s political patron, former President Alvaro Uribe, in September...
Unfortunately for Duque, the president also found himself investigated on election fraud charges and media revealed evidence of Duque’s ties to a drug trafficking organization in March.

How has such an unpopular president managed to stay in power?
America.

The U.S. government is no fan of the Special Jurisdiction for Peace (JEP). U.S Ambassador Kevin Whitaker in April 2019 insisted that if the JEP protected former guerrillas from extradition, Colombia would lose U. S. military assistance.

Sections of the U.S. government were already reluctant to accept the peace agreement, perhaps because of long-nurtured animus against the FARC. U.S. interventionists had jousted with the FARC off and on, in one way or another, since 1964. Pretexts evolved from anti-communism to drug war to narco-terrorism.
They most likely believed, with Colombian military colleagues, that the FARC insurgency must disappear, starting with military defeat.

If you think this is something new or the fault of the Trump, think again. President Biden might make things worse.

As Steven D. Cohen put it recently in The Baffler, “Plan Colombia was in effect to Global South pacification what the 1994 crime bill had been to domestic policing.”

This past January, during a primary campaign stop, Biden said to the Des Moines Register, “I’m the guy who put together Plan Colombia,” which, given the legacy of the plan, might sound like a confession, but was certainly meant as a boast.
... In perhaps the most obvious sign of failure, after the implementation of the plan, cocaine flowed northward at higher rates and lower prices than ever before. The other clear result was an increase in violence: Between 2003 and 2007, the Colombian army, funded and emboldened by the United States, killed thousands of civilians and falsely claimed they were guerrilla soldiers killed in combat, in what became known as the “false positives” scandal.
