New Books in Diplomatic History

President John F. Kennedy and Prime Minister Winston S. Churchill remain two of the most iconic figures of the twentieth century and Joel Nelson’s new book, Kennedy’s Only Hero: How JFK’s Obsession with Winston Churchill Defined His Presidency (Public Affairs, 2026), reveals the unexpected influence that Churchill had on Kennedy’s political career.
Winston Churchill remains one of the modern age’s most revered leaders. His life has been the subject of decades of mythmaking and scrutiny, and yet few know the powerful sway he had over another twentieth-century political icon―John F. Kennedy. Drawing on deep wells of unpublished archival material, Kennedy's Only Hero uncovers Kennedy’s obsession with Churchill, whose career, policies, writings, and even daily habits profoundly shaped the future president.
Kennedy discovered Churchill’s books as a teenager and by his early twenties had become an unswerving believer in his brilliance. Under Churchill’s influence, Kennedy rejected his own youthful isolationism and adopted the approach to national and international politics that propelled him to the presidency. Although they would not meet until late in their lives, Churchill’s influence on Kennedy’s campaign tactics, speeches, and worldview was overwhelming. Kennedy’s conviction in the power of peace through strength, his faith in summits, his understanding of the importance of rhetoric, and his deep commitment to service and global engagement―all came from Churchill.
Kennedy's Only Hero is an enlightening and deeply human story of an admiration and aspiration that changed the course of history.

Historians have always known that the success of the Allied invasion of Normandy on D-Day in June 1944 depended on deceiving the Germans about where the invasion would take place. Jason Bell’s book, Operation Sparrow: The Incredible True Story of the Spies Who Tricked Hitler and Won the War (Hanover Square Press, 2026), tells the story of how three secret agents got themselves captured in Hungary to convince the Third Reich that the Allied invasion was taking place a thousand miles away.
March 16, 1944. Colonel Duke jumped into Hitler's Europe to lead Operation Sparrow, an OSS mission authorized by the president. Duke was forty-eight, twice the age of most paratroopers. He had played pro football for the New York Giants, flown fighter planes, and made his fortune in advertising before World War II made him a spy behind enemy lines.
Within days, the three Sparrows were captured in Hungary. It wasn’t a failure. It was the plan. Under brutal Gestapo interrogation, Duke and his men set out to convince the Third Reich that the D-Day invasion would strike the Balkans, far from France.
Survive torture while making a lie sound true—it was either genius or suicidal. Probably both.
If the ruse held, Axis divisions would defend the wrong coast. If it broke, three Americans would be shot as spies—and the Wehrmacht would be poised to win D-Day.
Of the tens of millions who fought in the war, the Sparrows were the only ones whose mission required capture by the Nazis. Drawing on recently declassified OSS files, Jason Bell brings their story to life.
Operation Sparrow reveals:
The American heroes who turned their own capture into a weapon
The Gestapo interrogation rooms that became a secret Allied battlefield
The top-secret deception that kept Hitler's divisions away from Normandy
Meticulously researched and told at the pace of a thriller, Operation Sparrow is narrative history for readers of Operation Mincemeat and Unbroken.

From the dawn of the modern era to the end of the Cold War, global history was defined by rivalries between Great Powers. In the West, this meant the struggle for supremacy in Europe and the Americas, while in the East, it encompassed those vying for control over the successor states to Genghis Khan’s empire. Between 1989 and the year 2000, Great Power rivalry temporarily gave way to globalization, with liberal democracy on the march and national chauvinism seemingly in retreat. But events of the past decade have made one thing abundantly clear: The Great Powers are back.
In The Return of the Great Powers (Basic Books, 2026), renowned historian Brendan Simms offers a new history of the rise, fall, and return of the Great Powers in our time.  He shows that over the past ten years or so, the major global actors have already resumed making decisions based on geopolitical rather than global economic considerations.

Great Power Diplomacy. The Skill of Statecraft from Attila the Hun to Kissinger (Princeton UP, 2025) is a captivating history of diplomacy—and an urgent reminder of why we need to revive its lost arts to survive in a dangerous era of great power competition. From the beginning of time, human societies have found themselves confronted by enemies too numerous or ferocious to defeat solely by force of arms. In these dramatic moments, wise leaders have turned to diplomacy to rearrange the gameboard in their favor and stymie seemingly unstoppable foes. In Great Power Diplomacy, American historian and diplomat A. Wess Mitchell recounts the forgotten story of how history’s most legendary empires have used diplomacy as a tool of grand strategy to outwit, outmaneuver, and outlast militarily superior opponents. Through fifteen centuries of history, Great Power Diplomacy recreates the perilous junctures, colorful personalities, and intricate statecraft that led to some of history’s most stunning diplomatic achievements—and greatest disasters. The protagonists include giants like Richelieu, Metternich, Bismarck, and Kissinger, but also a lesser-known cast of scoundrels, eunuchs, drunkards, and fools. At every turn, fortune favored those great powers with the foresight and dexterity to build winning alliances, splinter enemy coalitions, and, when necessary, make peace with their bitterest foes. Diplomacy of this kind has become a lost art in recent years as Western elites embraced the illusion that globalization and the spread of democracy would create a borderless world where nations would live in harmony and war would be abolished from the human story. But, as Great Power Diplomacy reveals, we will need to rediscover the secrets of skillful statecraft as the world enters an unstable new era in which continent-sized great powers compete for territory, resources, and prestige. By recalling diplomacy’s rich past, we can equip ourselves for a more dangerous future.

When powerful states go to war, why do they bother asking permission? In Strategies for Approval: Building Support for Military Intervention at the UN Security Council (Yale University Press, 2025), Stefano Recchia argues that the answer reveals something surprising about how power actually works.
Drawing on hundreds of declassified documents and more than fifty interviews with senior diplomats, among them Andrei Kozyrev, Brent Scowcroft, and Colin Powell, Recchia shows that money and muscle are rarely enough to move a reluctant Security Council. States that succeed also reassure: they accept time limits, geographic restrictions, and multilateral oversight written directly into the resolutions they seek.
Our conversation traces that logic through France's controversial 1994 intervention in Rwanda, the six-week "pause for peace" the United States conceded to Gorbachev and Mitterrand before the First Gulf War, and the very different failure of 2003. Recchia also discusses what his interviews revealed about the real aims behind the 2011 intervention in Libya.
The more powerful a state becomes, this book shows, the more its power frightens others, and the more it must bind itself to get anything done.
