The country’s leader, Gustavo Petro, backed down after a clash with President Trump, which started when Mr. Petro turned back U.S. military planes carrying deportees.

Colombian President Gustavo Petro announced that Colombia was suspending permission for previously authorized U.S. deportation flights to land in Colombia. Ostensibly driving Petro’s action were concerns that Colombian nationals were not being treated with respect during the deportation process because they were being transported by military aircraft.

The diplomatic drama that began over the weekend provided clues on how Trump would deal with countries standing in the way of his immigration policies.
