“President Trump wants to deploy a blunt new tool to fight Mexican cartels that flood the U.S. with drugs, by adding them to a list of terrorist groups that includes the likes of al Qaeda and Hamas. The move could increase pressure on the cartels by directing more money to intelligence gathering. It could also lay the groundwork for going after cartel financiers and allied businesses—and for unilateral U.S. military action such as drone strikes on drug labs, according to officials and security experts. But even without direct U.S. intervention, adding cartels to the terrorism list risks straining ties with Mexico, at a time when the two countries are in delicate talks over ending drug smuggling and migration to avoid a trade war.”
