Trump Turns Up Heat on Latin America

President Trump’s vow to intervene against drug smugglers in Colombia widened a U.S. counternarcotics campaign in Latin America that began with military strikes on oceangoing boats but is increasingly focused on threatening governments in the region.

His broadside against Colombia came in a social-media post Sunday morning that branded its president, Gustavo Petro, an “illegal drug leader,” vowing to halt U.S. aid to Bogotá, and to take unilateral action unless Petro closed “these killing fields immediately.”
