New Books in National Security

Since the beginning of the twentieth century, governments around the world have expelled, en masse, more than 30 million people. Yet despite its prevalence, mass expulsion remains an understudied phenomenon as scholarly attention has been directed toward the gravest atrocities—genocide and mass killing—or toward forced migration more broadly.

Mass Expulsion: The Politics of Forced Population Removal (Oxford UP, 2026) by Dr. Meghan Garrity examines why and how governments expel, providing a systematic, cross-regional account of mass expulsion over the longue durée. Using the original Government-Sponsored Mass Expulsion (GSME) dataset, the book explains when and where expulsion occurs, who is targeted, and what regimes are most likely to expel. The book identifies two overarching categories of mass expulsion—security and economic—and develops a typology of four corresponding types: counter-irredentist, counter-subversive, reprisal, and nativist. It advances a theory of mass expulsion that traces the decision-making process, showing how key structural, proximate, precipitating, and intervening factors combine to shape the conditions under which governments expel or are restrained. Evidence is drawn from archival research conducted at the United Nations High Commissioner for Refugees, the International Committee of the Red Cross, and the League of Nations archives in Geneva, Switzerland.This research contributes to the fields of international peace and security, political violence, and forced migration. Conceptually, it fills a gap in the literature by systematically examining mass expulsion as a distinct eliminationist policy aimed at the intentional removal of ethnic groups. Theoretically, it extends existing explanations beyond war and security threats, highlighting an entire class of expulsions targeting perceived economic threats. The book deepens our understanding of critical atrocity restraints, demonstrating the importance of alliances, the “homeland” state of the target group, and international organizations. These restraints generate core policy recommendations that seek to spur greater attention to deterring mass expulsion as a priority for atrocity prevention.

After
Soviet cipher clerk Igor Gouzenko defected in 1945, Canada was shocked
by the revelation that its own citizens were engaged in espionage for
the Soviet Union. "P.S. Burn after Reading": The Kellock-Taschereau Commission and Soviet Espionage in Canada
(University of Toronto Press, 2026) explores how the Canadian
government used the controversial Kellock-Taschereau
Commission—sometimes judiciously, sometimes not—to uncover and thwart
domestic
spies during the early days of the Cold War.

Drawing
on a wealth of sources, including the Commission’s extensive records,
GRU documents turned over by Gouzenko, American Venona decrypts, Soviet
KGB archives, and newly released British MI5 and MI6 files, authors Dr.
Reinhold Kramer and Dr. Tom Mitchell provide a comprehensive account of
the crisis. They reveal that, despite some civil liberties missteps, the
government’s suspicions were largely justified.

The
book weaves together the evidence against the spies, the tradecraft of
Soviet espionage, complex legal challenges faced by the state, and the
political fallout. With access to hundreds of newly released British
intelligence files, P.S. Burn After Reading
offers both specialists and general readers fresh insights into the
espionage crisis of 1945–46 and the pivotal role it played in exposing
Canada’s postwar security and intelligence vulnerabilities.

negotiation and implementation in civil war contexts, with qualitative
analysis of the Angolan and Mozambican civil wars. You can find

Purges: How Dictators Fight to Survive
(Cornell University Press, 2026) by Dr. Edward Goldring delves into one
of the key tactics that autocrats deploy to maintain power: the removal
of individuals from within the regime.

From Kim Jong Un's
execution of his uncle to Recep Tayyip Erdoğan's removal of over a
hundred Turkish generals, purges bear significant consequences for the
survival and endurance of autocrats. Yet much remains unknown about why
dictators use purges and whether they achieve their intended effects.

Drawing
on an original global dataset on civilian and military elite purges in
dictatorships in addition to case studies spanning North and South Korea
as well as Turkey, Dr. Goldring examines the logic behind purges and
their consequences. He shows that dictators purge to consolidate power,
punish disloyalty, and scapegoat elites to alleviate popular threats.
But even as purges help dictators consolidate power early in their
tenure, purges actually weaken
their position when they have been in power for a long time, prompting
pushback. In the face of an increasing global shift toward authoritarian
norms, Purges offers critical insight into how autocrats maintain—and sometimes lose—power.

Steve Feldstein's Bytes and Bullets: Global Rivalries, Private Tech, and the New Shape of Modern Warfare (St. Martin's Press,
2026) opens with a juxtaposition: China spending vast sums to reach the
far side of the moon, and Ukraine using cheap drones to blunt a far
larger military. Both are stories about technology and power, but they
point in opposite directions.

In our conversation, Feldstein
argues that the outcome of technological competition is not
predetermined. Small states, non-state actors, and private companies
with the right engineers can now challenge much stronger adversaries. We
discuss Iran, whose military innovation grew out of decades of
sanctions rather than in spite of them, and why Western analysts
dismissed what was in plain sight. We then turn to China and Feldstein's
concern that the United States is making unforced errors, hollowing out
the basic research on which its edge depends.

Bytes and Bullets
resists both technological determinism and the claim that nothing has
changed. But this book is also candid about what cannot be predicted: as
machines take on decisions humans once made, who, if anyone, will set
the limits?

Our guest is Steven Feldstein, a senior fellow at the Carnegie Endowment for International Peace in the Democracy, Conflict, and Governance Program.

Our host is Eleonora Mattiacci, an Associate Professor of Political Science at Amherst College. She is the author of "Volatile States in International Politics" (Oxford University Press, 2023).

The strategic landscape of the Cold War generated political support for a permanent US military force of unprecedented scale. Faced with the problem of managing this behemoth, leaders of the defense bureaucracy looked to private industry for inspiration: since the military now resembled a huge industrial conglomerate, they reasoned, it should be run like a business. In Pentagon Capitalism: How the Cold War US Military Modeled Itself on Private Business (Harvard UP, 2026), Dr. A. J. Murphy explores the profound consequences of translating military structures of command, logistics, and warfare into capitalist terms.In the realm of budgeting and finance, defense reformers refashioned the supply process as a buy-and-sell transaction between units, requiring officers to express their need for equipment and labor in dollar terms. Bureaucrats embraced Taylorist work measurement to supervise everything from clerical filing to the production of massive weapons systems. The services even engaged management consultants to establish officer-training academies modeled on the Harvard Business School.After the Vietnam War, many military leaders pushed back, questioning “managerialism” and calling for a return to traditional concepts of command. Civilian critics also chimed in, protesting the callousness of the business-minded secretary of defense, Robert McNamara, who famously measured success and failure in body counts. By this time, however, the language and values of management had thoroughly infiltrated the military’s institutional structure and daily operations. As Pentagon Capitalism makes clear, the reorganization of the defense bureaucracy along the lines of a for-profit firm durably altered the experience of military work and facilitated the lasting privatization of US national security.
