Who's winning the war on drugs?

Mexico's cartels are thriving, and finding innovative ways to smuggle drugs across the border into the US, despite law enforcement and the pandemic.Ed Butler speaks to Dr Irene Mia of the International Institute for Strategic Studies, who says the closing of borders due to Covid has provided the cartels with a surprising shot in the arm, as they have proved far more adept at keeping their product flowing than many other legitimate international export businesses. Speedboats, tunnels, even catapults have been deployed to get methamphetamine and fentanyl into the US.And that's not all. The cartels have diversified, into people smuggling, wildcat mining and crude oil theft among other things, according to the Mexico-based author and journalist Ioan Grillo. And they aren't the only ones. In Brazil, a narcotics gang called First Capital Command has become so powerful that they have effectively replaced the government in some parts of the country, according to Marcos Alan Ferreira of the Federal University of Paraiba.(Picture: Mexican Federal Police officers patrol Iguala, Guerrero state, Mexico; Credit: Yuri Cortez/AFP via Getty Images)
