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.

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.

President Donald Trump appeared to win Sunday’s showdown with Colombia, after Colombia appeared to accept military flights carrying deportees. But the faceoff could herald more conflict.
