Against the sprawling backdrop of the Cold War, The Kremlinologist revisits some of the twentieth century's greatest conflicts as seen through the eyes of its hardest working diplomat, Llewellyn E Thompson. From the wilds of the American West to the inner sanctums of the White House and the Kremlin, Thompson became an important advisor to presidents and a key participant in major global events, including the Cuban Missile Crisis and the Vietnam War. Yet unlike his contemporaries Robert S. McNamara and Dean Rusk, who considered Thompson one of the most crucial Cold War actors and the "unsung hero" of the Cuban Missile Crisis, he has not been the subject of a major biography-until now. Thompson's daughters Jenny and Sherry Thompson skillfully and thoroughly document his life as an accomplished career diplomat. In vigorous prose, they describe how Thompson joined the Foreign Service both to feed his desire for adventure and from a deep sense of duty. They also detail the crucial role he played as a negotiator unafraid of compromise. Known in the State Department as "Mr. Tightlips," Thompson was the epitome of discretion. People from completely opposite ends of the political spectrum lauded his approach to diplomacy and claimed him as their own. Refuting historical misinterpretations of the Berlin Crisis, the Austrian State Treaty, and the Cuban Missile Crisis, the Thompsons tell their father's fascinating story. With unprecedented access to Thompson's FBI dossier, State Department personnel files, letters, diaries, speeches, and documents, and relying on probing interviews and generous assistance from American and Russian archivists, historians, and government officials, the authors bring new material to light, including important information on the U-2, Kennan's containment policy, and Thompson's role in US covert operations machinery. This unique and monumental biography not only restores a central figure to history, it makes the crucial events he shaped accessible to a broader readership and gives contemporary readers a backdrop for understanding the fraught United Statesâ Russia relationship that still exists today.
