Roosevelt's Lost Alliances

Frank Costigliola's "Roosevelt's Lost Alliances: How Personal Politics Helped Start the Cold War" offers a detailed examination of the diplomatic relationships that shaped the final years of World War II and the uneasy transition into the Cold War era. Rather than treating high-level diplomacy as a purely strategic or ideological affair, Costigliola places emphasis on the personal dimensions of statecraft: the friendships, resentments, health struggles, and emotional dynamics that influenced how leaders and diplomats interacted with one another. This approach distinguishes the book from more conventional accounts of the period, which tend to focus primarily on policy decisions and geopolitical calculations.

The central argument of the book is that the alliance forged between Franklin D. Roosevelt, Winston Churchill, and Joseph Stalin during the war was built not only on shared strategic interests but also on a fragile web of personal rapport. Roosevelt, in particular, is portrayed as someone who relied heavily on his own charm and ability to read people, believing that his personal relationship with Stalin could help manage postwar tensions between the United States and the Soviet Union. Costigliola traces how Roosevelt's declining health in the final months of his life, combined with the deaths or removal of key diplomats who had cultivated working relationships with Soviet counterparts, contributed to a breakdown in mutual understanding after his death.

One of the book's strengths lies in its attention to specific individuals whose roles are often overlooked in broader histories of the period. Diplomats such as Averell Harriman, Charles Bohlen, and others are given careful treatment, with Costigliola illustrating how their personal temperaments, ambitions, and interactions with Soviet officials shaped the tone of diplomatic exchanges. The author draws on personal letters, diaries, and diplomatic cables to reconstruct not just what these figures decided, but how they felt about the decisions they were making and the people with whom they were negotiating. This method allows the book to present a more textured picture of wartime diplomacy, one in which emotions and personal judgments played a tangible role in shaping outcomes.

Costigliola also pays close attention to Roosevelt's successor, Harry Truman, and the shift in tone that accompanied the change in leadership. Truman lacked the personal history with Stalin that Roosevelt had cultivated, and the book suggests that this absence of established rapport, combined with a more suspicious and less personally engaged approach to Soviet relations, hastened the deterioration of wartime cooperation. The narrative does not claim that personal relationships alone caused the Cold War, but rather that the erosion of these relationships removed a stabilizing element that had previously helped manage disagreements between the wartime allies.

The book is grounded in extensive archival research, and Costigliola's background as a historian specializing in American foreign relations is evident throughout. The prose is generally accessible, though the density of names, dates, and diplomatic details may require careful reading, particularly for those less familiar with the personnel involved in wartime diplomacy. The book assumes a baseline familiarity with the broader chronology of World War II and its aftermath, which allows Costigliola to focus his attention on the interpersonal dynamics that are the book's central subject.

What emerges from this study is a more human portrait of a pivotal historical transition, one that resists simple narratives of inevitable conflict between the United States and the Soviet Union. Instead, Costigliola presents a picture of contingency, in which different personal choices, different health outcomes, and different diplomatic appointments might have led to a different postwar trajectory. This perspective does not diminish the importance of ideological and strategic factors in the origins of the Cold War, but it adds a valuable layer of complexity by showing how individual relationships and emotional judgments intersected with larger historical forces.

Overall, "Roosevelt's Lost Alliances" is a thoughtful and well-researched contribution to the historiography of the early Cold War period. It will likely appeal most to readers with an existing interest in diplomatic history, World War II, or the Roosevelt administration, offering them a fresh angle on a familiar story through its focus on the personal side of international politics.
