North Korea's Nuclear Posture: an Evolving Challenge for U.S. Deterrence
A more capable, nuclear-armed, North Korea will pose very substantial challenges to the U.S. deterrence posture.
While North Korea’s nuclear program already serves multiple functions in its security strategy, it is likely to acquire an even greater role over the coming years. Once the regime deploys more advanced nuclear weapons and ballistic missiles, it might be tempted to pursue a revisionist agenda focusing either on the reunification of the Korean peninsula or on more limited aims. In support of such ambitions, Pyongyang may develop a theory of victory relying on the threat of nuclear escalation to deter enemies from pursuing regime change and to compel them to accede to its demands. As North Korea’s capabilities mature, the United States, South Korea, and Japan will need to articulate a comprehensive approach to deterring Pyongyang while managing their differences to respond to North Korea’s behavior during peacetime, crisis, and conflict. To deter Pyongyang, coordination is key, hence the need for the United States and its allies to adopt a layered deterrence strategy and determine courses of action that, if pursued vigorously and carefully, would increase their chances of containing a nuclear-armed North Korea and avoiding nuclear war.

Security Studies Center
Heir to a tradition dating back to the founding of Ifri, the Security Studies Center provides public and private decision-makers as well as the general public with the keys to understanding power relations and contemporary modes of conflict as well as those to come. Through its positioning at the juncture of politics and operations, the credibility of its civil-military team and the wide distribution of its publications in French and English, the Center for Security Studies constitutes in the French landscape of think tanks a unique center of research and influence on the national and international defense debate.
Deterrence and Proliferation
The conflicts in Europe, Asia and the Middle East demonstrate a return of nuclear power to the balance of power. Arsenals are being modernized and expanded, while arms control is collapsing. This research program aims to analyze these phenomena.

Return to the East: the Russian Threat and the French Pivot to Europe's Eastern Flank
Russia’s full-scale invasion of Ukraine on February 24, 2022, has flung Europe’s Eastern flank into a new phase of strategic confrontation. It has had a major effect on France’s position, which was previously somewhat timid, leading it to significantly reinforce its deterrence and defense posture in support of the collective defense of Europe, in the name of strategic solidarity and the protection of its security interests.
Military Stockpiles: A Life-Insurance Policy in a High-Intensity Conflict?
The war in Ukraine is a reminder of the place of attrition from high-intensity conflict in European armies that have been cut to the bone after three decades of budget cuts. All European forces have had to reduce their stocks to the bare minimum. As a result, support to Ukraine has meant a significant drain on their operational capabilities. A significant amount of decommissioned systems were also donated, due to the lack of depth in operational fleets.

With a rapidly deteriorating security environment, a chaotic withdrawal from Afghanistan, internal disputes exploding into public view, and questions being raised about the scope of its security responsibilities, the North Atlantic Treaty Organization (NATO) seemed to be in dire straits at the time of Russia’s invasion of Ukraine on February 24, 2022.
