Damien Van Puyvelde, "The DGSE: A Concise History of France's Foreign Intelligence Service" (Georgetown UP, 2026) New Books in National Security

France is a leading intelligence power, but we know very little about its premier intelligence agency: the Direction Générale de la Sécurité Extérieure (DGSE). Damien Van Puyvelde's latest book, The DGSE: A Concise History of France's Foreign Intelligence Service (Georgetown University Press, 2026), examines France's foreign intelligence service from its rebranding as the DGSE in 1982 to the present. It covers the legacies of the Second World War, how decolonization and the Cold War shaped the organization, the organization's workforce and leadership, as well as public and (pop) cultural perceptions and representations of intelligence in France. The emergence of the DGSE, following the election of socialist President Mitterrand, opened an era of change, marked by a series of reorganizations and new threats over the horizon. Some readers will recall the Rainbow Warrior fiasco, when DGSE operators sank Greenpeace's flagship, causing the death of a photographer in 1985. Others will be more familiar with the popular TV show The Bureau, which portrays the lives of non-official cover DGSE officers operating in contemporary hotspots. These vignettes, just like much of the media coverage, paint a misleading portrait of the DGSE as a group of dedicated but reckless officers. Van Puyvelde shows how France's leading intelligence agency has successfully adapted to political and security requirements from the late Cold War to today's international security threats.
