New Books in Diplomatic History

Dropping the atomic bombs on Japan during World War II was, arguably, the most controversial decision of the 20th century. The responsibility for that “decision” has logically fallen on US President Harry S. Truman. But in The Most Awful Responsibility: Truman and the Secret Struggle for Control of the Atomic Age (Harper, 2025), Alex Wellerstein argues that Truman's actual decision wasn’t what everyone thinks it was.

The conventional narrative is that American leaders had a choice: Invade Japan, which would have cost millions of Allied and Japanese lives, or instead, use the atom bomb in the hope of convincing Japan to surrender. Truman, the story goes, carefully weighed the pros and cons before deciding that the atomic bomb would be used against Japanese cities, as the lesser of two evils.

But nuclear historian Alex Wellerstein argues that is not what happened.

Not only did Truman not take part in the decision to use the bomb, but the one major decision that he did make was a very different one — one that he himself did not fully understand until after the atomic bomb was used. The weight of that decision, and that misunderstanding, became the major reason that atomic bombs have not been used again since World War II.

Based on a close reading of the historical record, The Most Awful Responsibility shows that, despite his reputation as an ardent defender of the atomic bomb, Truman:

Wanted to avoid the “murder” and “slaughter” of innocent civilians

Believed that the atomic bomb should never be used again

Hoped that nuclear weapons would be outlawed in his lifetime

Wellerstein makes a startling case that Truman was possibly the most anti-nuclear American president of the twentieth century, but his ambitions were strongly constrained by the domestic and international politics of the postwar world and the early Cold War. This book is a must-read for all who want to truly understand not only why the bomb was dropped on Japan but also why it has not been used since.

In The Price of Truth: The Journalist Who Defied Military Censors to Report the Fall of Nazi Germany (Cornell, 2023), Richard Fine recounts the intense drama surrounding the German surrender at the end of World War II and the veteran Associated Press journalist Edward Kennedy’s controversial scoop.

On May 7, 1945, Kennedy bypassed military censorship to be the first to break the news of the Nazi surrender executed in Reims, France. Both the practice and the public perception of wartime reporting would never be the same. While, at the behest of Soviet leaders, Allied authorities prohibited release of the story, Kennedy stuck to his journalistic principles and refused to manage information he believed the world had a right to know. No action by an American correspondent during the war proved more controversial.

The Paris press corps was furious at what it took to be Kennedy’s unethical betrayal; military authorities threatened court-martial before expelling him from Europe. Kennedy defended himself, insisting the news was being withheld for suspect political reasons unrelated to military security. After prolonged national debate, when the dust settled, Kennedy’s career was in ruins.

This story of Kennedy’s surrender dispatch and the meddling by Allied Command, which was already being called a fiasco in May 1945, revises what we know about media-military relations. Discarding “Good War” nostalgia, Fine challenges the accepted view that relations between the media and the military were amicable during World War II and only later ran off the rails during the Vietnam War. The Price of Truth reveals one of the earliest chapters of tension between reporters committed to informing the public and generals tasked with managing a war.

Since the dawn of the twenty-first century, the West has been in crisis. Social unrest, political polarization, and the rise of other great powers—especially China—threaten to unravel today’s Western-led world order. Many fear this would lead to global chaos. But the West has never had a monopoly on order.Surveying five thousand years of global history, political scientist Amitav Acharya reveals that world order—the political architecture enabling cooperation and peace among nations—existed long before the rise of the West. Moving from ancient Sumer, India, Greece, and Mesoamerica, through medieval caliphates and Eurasian empires into the present, Acharya shows that humanitarian values, economic interdependence, and rules of inter-state conduct emerged across the globe over millennia. History suggests order will endure even as the West retreats. In fact, the end of Western dominance offers us the opportunity to build a better world, where non-Western nations find more voice, power, and prosperity. Instead of fearing the future, the West should learn from history and cooperate with the Rest to forge a more equitable order.

Rachel Midura joins Jana Byars to talk about Postal Intelligence: The Tassis Family and Communications Revolution in Early Modern Europe (Cornell UP, 2025) connects and situates histories of the post and government intelligence alongside print technology and state power in the wider context of the early modern communications revolution. In the sixteenth century, postal services became central to domestic governance and foreign policy enterprises, extended government reach and surveillance, and offered new control over the public sphere. Rachel Midura focuses on the Tassis family, members of which served as official postmasters to the dukes of Milan, the pope, Spanish kings, and Holy Roman emperors. Using administrative records and family correspondence, she follows the Tassis family, their agents, and their rivals as their influence expanded from northern Italy across Europe. Postal Intelligence shows how postmasters and postmistresses were key players in early modern diplomacy, commerce, and journalism, whose ultimate success depended on both administrative ingenuity and strategic ambiguity.
