Rubio doubtful of diplomacy with Cuba as Trump raises new threat of military action

President Trump and Secretary of State Marco Rubio have renewed threats of U.S. military intervention in Cuba, with Rubio expressing skepticism about achieving a diplomatic resolution with the island's current government. The threats come after the U.S. announced criminal charges against former Cuban leader Raúl Castro for ordering the 1996 shootdown of civilian planes, and follow failed diplomatic talks between U.S. and Cuban officials.
