«“A carefully researched account of Guillermo Belt and his impact on Cuba diplomacy. Well written and comprehensive, this book sheds light on and makes a significant contribution to the understanding of an important and little researched period of Cuban history.”»

Jaime Suchlicki, professor emeritus and director, Cuban Studies Institute

«In presenting the life of Guillermo Belt, Daniel Pedreira has done a great service to Cuban, and indeed Latin American History, and taken an important step in dismounting the Castro Dictatorship´s effort to conceal and rewrite the past. Belt was part of a remarkable cadre of Cuban diplomats who served their country with honor and distinction during turbulent times both in Cuba and the World, since Independence in 1902 until the advent of Tyranny, in 1959. Furthermore, Belt´s career in exile highlights his sense of duty and commitment to his country and to future generations of Cubans. I enthusiastically recommend "An Instrument of Peace" . It is required reading for anyone interested in understanding the true history of Cuba and what the future may hold the day that the country has again joined the ranks of democratic societies.»

Aurelio Fernandez-Concheso M., author of "El Diplomatico- de la Gran Depresión a la Guerra Fría"

«“A much deserved recognition to one of Cuba’s most distinguished diplomats. Well researched and detailed, this book provides a warm yet unapologetic portrayal of Guillermo Belt and his times”.»

Luis G. Solís, Florida International University

«Even in the darkest of times, wrote Hannah Arendt in the preface of one her books, "we have the right to expect some illumination", and "such illumination may well come less from theories and concepts than from the uncertain, flickering and often weak light that some men and women, in their lives and their works, will kindle under almost all circumstances and shed over the time span that was given them on earth...." There is a number of courageous individuals in the Cuban history of the 20th century, whose life story is endowed with such a illuminating power and Ambassador Guillermo Belt is undoubtedly one of them. This book is essential reading for anyone who wants to eliminate once for all the adversarial effects of Orwellian memory hole created by the six decades of communist rule imposed on Cuba by Fidel Castro and work for the rebirth of Cuban political nation – free and prosperous, capable to rediscover and assess critically its past and find its proper place in the today’s world, alongside with other Latin American liberal democracies, within the family of nations struggling together against all totalitarian tendencies the global humanity is exposed to in the first decades of the 21st century.»
