It was a cool night for Havana, with the temperature falling into the mid-70s, and the diplomat and his family were feeling very good about their assignment to Cuba. They were still settling into their new home, a comfortable, Spanish-style house in the lush enclave that had been called “el Country Club” before wealthy families abandoned it in the early years of the revolution. “We were just thrilled to be there,” the diplomat recalled. “The music, the rum, the cigars, the people — and a very important moment for diplomacy.”
Eight months earlier, in March 2016, President Barack Obama had swept into town to commemorate the two countries’ historic rapprochement, vowing to bury “the last remnant of the Cold War in the Americas.” Now, weeks after the election of Donald Trump, that entente was suddenly doubtful. Fidel Castro had just died, opening a new chapter in the Cuban saga. The diplomat could hardly have imagined a more fascinating time to arrive.
