President Donald Trump called Cuba a “failed state” during his address to the United Nations General Assembly on Tuesday and warned that the country will fall, prompting members of the Cuban delegation to walk out of the chamber.

President Trump has repeatedly criticized Cuba’s communist government and has increased pressure on Havana during his second term. In May, he described Cuba as a failed country and said it was “only heading in one direction” while indicating that his administration would eventually engage with the island.

Trump's remarks at the U.N. came as Cuba faces a severe economic and energy crisis. The island experienced another nationwide electrical grid collapse on Sept. 18, leaving millions without power and adding to a series of blackouts that have plagued the country throughout the year.

The Trump administration has also increased its focus on Cuba as a national security issue. Secretary of Defense Pete Hegseth previously told Congress that he considers the Cuban regime a national security threat, while U.S. military officials have held talks with Cuban counterparts near Guantanamo Bay amid heightened tensions.

Trump’s comments at the U.N. add to his administration’s broader pressure campaign against Havana, which has included additional financial sanctions and restrictions involving travel and remittances. The administration has also sought changes from the Cuban government while offering humanitarian assistance to the Cuban people
