When Colombia’s president, Gustavo Petro, refused military planes carrying deportees, infuriating President Trump, he revealed how heated the question of deportations has become.

Two Colombian air force planes carrying deportees from the United States arrived in Bogota on Tuesday, the government said, paving the way for U.S. President Donald Trump's administration to lift visa restrictions and other measures on Colombian citizens.

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.

Two of President Donald Trump’s deportation flights to Colombia were packed full of innocent people, according to officials in the South American country. On Sunday, Jan. 26, Trump threatened Colombia with crippling tariffs,

The Government of Colombia, under the direction of President Gustavo Petro, has arranged the presidential plane to facilitate the dignified return of the compatriots.”

The move followed a dispute between President Trump and President Gustavo Petro over deportation flights that nearly turned into a costly trade war between both countries.

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.
