The U.S. broke relations with Cuba on this day, and closed its embassy. Fifty-three-years later, on Wednesday, Dec. 17, 2014, the U.S. and Cuba agreed to re-establish diplomatic relations and open economic and travel ties, marking a historic shift in U.S. policy toward the communist island after a half-century of enmity dating back to the Cold War.
