The Trump administration added Colombia to a list of countries failing to cooperate in the war on drugs for the first time in nearly 30 years.

The designation reflects the deteriorating relations between the United States and one of its closest Latin American allies. Trump’s vision has repeatedly clashed with that of the left-wing president, Gustavo Petro, whose approach to cocaine production has failed to stop the skyrocketing of cocaine cultivation. In a presidential determination, Trump laid the deterioration in relations at Petro’s feet.
