Colombian Ex-president Uribe was against the FARC peace treaty. My guess is that it's related to (1) most of the drugs are grown in areas controlled by Anti-FARC paramilitaries, allied to the government and (2) a number of Uribe's close family are in prison convicted of connections to said paramilitaries (see links for some sources for these claims). Keeping the FARC around was convenient political cover for neo-nazi drug-cartels closely allied to the army, police and ruling political party.
Here's a timeline for 2008 in Colombia. In early 2008, Uribe was facing scandals related to his family's involvement with drug-trafficking death squads. Shortly after, Uribe's forces kill the FARC's peace negotiator, Raul Reyes, then after that, Uribe takes the credit for ordering a "daring" raid to rescue Ingrid Betancourt, a FARC hostage for several years.
https://www.theguardian.com/world/2008/apr/23/colombiahttps://en.wikipedia.org/wiki/Operation_JaqueFirstly, Raul Reyes was actually working on getting Ingrid Betancourt released at the time of his death. Uribe's forces therefore allowed him to take military credit for something that would have happened anyway, without bloodshed.
Secondly, it came out that there was no "raid" at all. Leaked footage shows FARC militia merely handing over Ingrid Betancourt (and some other prisoners) to Colombian army officers illegally disguised as International Red Cross members. Uribe then changed his story: they'd infiltrated FARC's command structure and were able to trick them into doing a prisoner transfer (via the Red Cross apparently). However, the question must be asked: exactly how long had Uribe had these infiltrators in place? Ingrid Betancourt was kidnapped in 2002, while she was
running against Uribe for the presidency, then a few years later he conveniently snaps his fingers and gets her released. Both occurred at opportune times in Uribe's political career, and Uribe apparently had an easier time getting her out without a fight than a number of senior FARC people such as Reyes who were trying to negotiate the same thing. It's all too convenient.
(as an aside, when people pointed out that if the guerillas handed over prisoners to the International Red Cross then they were in fact
releasing the prisoners not merely
transporting the prisoners, Uribe tried to lump the International Red Cross in with the terrorists saying the FARC expected the Red Cross to merely help them move prisoners around. I'm 100% sure this is bullshit and the Red Cross doesn't in fact assist hostage-taking terrorists. But this is standard rhetoric from the Colombian right: all types of journalists, NGOs, unions, human rights activists, etc, are in league with the terrorists).

"Newsweek, May 21, 2001: “Colombian intelligence sources now estimate that 40 percent of the country’s total cocaine exports are controlled by these right-wing warlords and their allies in the narcotics underworld.” San Francisco Chronicle, June 21, 2001: “The Colombian government’s planning department estimates that FARC earns $290 million yearly from the drug trade. That represents less than 2.5 percent of the value of Colombia’s estimated annual cocaine output of 580 tons.” "
This was the FARC at their absolute
peak of power, as well, before Uribe got elected. So, right wing = drugs in Colombia but their propaganda is to blame the Left for the whole shebang. I've see Docos where DEA guys go deep into FARC-controlled areas to destroy coca crops. This is corrupt politcal BS at it's worst. They're just taking out the competition while tacitly leaving the government-allied nazi drug lords alone.
