In this March 21, 2016 file photo, Cuban President Raul Castro, right, lifts up the arm of U.S. President Barack Obama at the conclusion of their joint news conference at the Palace of the Revolution in Havana, Cuba. While Raul has been the face of communist Cuba, its defiance of U.S. efforts to oust its socialist system and its efforts to forge a rapprochement with its longtime foe for the past decade, he formally announced on Friday, April 16, 2021 that he'd step down as head of the Communist Party, leaving Cuba without a Castro in an official position of command for the first time in more than six decades.
