Book excerpt: History is being made in U.S.-Cuban relations. Now in paperback and updated to tell the real story behind the stunning December 17, 2014, announcement by President Obama and President Castro of their move to restore full diplomatic relations, this powerful book is essential to understanding ongoing efforts toward normalization in a new era of engagement. Challenging the conventional wisdom of perpetual conflict and aggression between the United States and Cuba since 1959, Back Channel to Cuba chronicles a surprising, untold history of bilateral efforts toward rapprochement and reconciliation. William M. LeoGrande and Peter Kornbluh here present a remarkably new and relevant account, describing how, despite the intense political clamor surrounding efforts to improve relations with Havana, negotiations have been conducted by every presidential administration since Eisenhower's through secret, back-channel diplomacy. From John F. Kennedy's offering of an olive branch to Fidel Castro after the missile crisis, to Henry Kissinger's top secret quest for normalization, to Barack Obama's promise of a new approach, LeoGrande and Kornbluh uncovered hundreds of formerly secret U.S. documents and conducted interviews with dozens of negotiators, intermediaries, and policy makers, including Fidel Castro and Jimmy Carter. They reveal a fifty-year record of dialogue and negotiations, both open and furtive, that provides the historical foundation for the dramatic breakthrough in U.S.-Cuba ties.
