Europe is Quietly Debating a Nuclear Future Without the US
America has protected Europe with is nuclear umbrella for more than 70 years. In the era of Vladimir Putin and Donald Trump, the continent is quietly debating a different nuclear future.
Chinese Nuclear Force Modernization and Doctrinal Change
Dating back to the first test in 1964, the Chinese nuclear force modernization process is motivated by other nuclear powers’ modernization across the years, mostly from the United States and the Soviet Union, but also by domestic factors such as economic debates and tensions in the scientific community.
Arctic: Toward the End of the Exception? Strategic, Nuclear and Maritime Issues in the Region
Through multiple international initiatives, including the creation of the Arctic Council at the end of the Cold War in 1996, the Arctic appears to be one of the last areas of peaceful cooperation in the world. This “Arctic exception” is also devoid of any serious territorial dispute between the neighboring countries, some of which are nevertheless great powers: Russia, the United States, Canada, but also Sweden, Norway, Denmark (via Greenland), Iceland and Finland.
Uranium in Namibia: Yellowcake Fever
Mineral revenues are the driving force behind Namibia’s economic performance. Namibia is rich in mineral resources which include uranium, diamond, copper, gold, lead, lithium and zinc. However, these mineral riches are not always allocated and utilized in a transparent manner and seem to benefit disproportionately a small number of wealthy elites, many of them affiliated with the ruling party SWAPO.
Hypersonic Weapons: What Are the Challenges for the Armed Forces?
Hypersonic systems are becoming attributes of power for the states that design and implement them, at the risk of reviving an arms race.
Strategic Risk Reduction between Nuclear-Weapons Possessors
The topic of nuclear risk reduction has gained momentum in the international security debate among policymakers, nongovernmental organizations, and experts.

French Defence Policy Since the End of the Cold War
With a look at evolutions over the past three decades, the thematic chapters cover French defense institutions and civil-military relations, the transformation of armed forces, nuclear deterrence, the defense industry, military interventions, and alliances.
The European Equation of Nuclear Deterrence, Variables and Possible Solutions
Ever since nuclear weapons were developed by the United States and the Union of Socialist Soviet Republics, Europe has lived under the nuclear shadow. A major direct confrontation between “the West” and “the East” could have very likely resulted in the detonation of nuclear weapons on the continent. As the Cold War ended, massive reductions in the US and Soviet arsenals (from 70,300 in 1986 to 13,890 in 2019) and a new security architecture radically transformed the European security environment.
Nuclear Multipolarity: Myths and Realities of Competition
The term “arms race” does not accurately reflect the events of the Cold War, let alone the multipolar logics that have followed it.
The Strategic Role of Land Forces: A French Perspective
Although the first and foremost domain in the history of warfare, Land power has been dissociated from the concept of “strategic forces” for some time now, as these generally referred to long-range and/or high-yield strike capabilities, above all nuclear weapons.
Tailored Assurance: Balancing Deterrence and Disarmament in Responding to NATO-Russia Tension
The 2018 Nuclear Posture Review (NPR) called for tailoring assurance across America’s allies, including NATO, as part of an overall deterrence and assurance strategy.
La guerre nucléaire limitée : un renouveau stratégique américain
Over the past few years, a debate on possible scenarios of limited nuclear weapons use has surfaced again in the United States. Russian nuclear saber-rattling since 2014 and the growing tensions in the Korean peninsula have led Washington to reassess its own ability to deter, or respond to, such a limited use of nuclear weapons.
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.
The NPT and the Origins of NATO’s Nuclear Sharing Arrangements
Russia has recently accused the United States and NATO Allies of violating the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) by arguing that NATO's nuclear sharing arrangements are not permitted under the Treaty.
Conventionalizing Deterrence? U.S. Prompt Strike Programs and Their Limits
About a decade ago, the U.S. started to examine options to develop and acquire Conventional Prompt Global Strike capabilities. This move fits in an effort to conventionalize deterrence, an effort initiated decades before and undertaken for profound and diverse motives. Although it has been renewed under the Obama administration, which aims to reduce the U.S. reliance on nuclear weapons, this ambition has resulted in very little concrete progress.
The Primacy of Alliance: Deterrence and European Security
Since the end of the Cold War, the international security environment has been transformed and nuclear weapons have been marginalized in the West. However, the NATO security policies remain almost unchanged: deterrence is still considered as a principle guiding the Atlantic Alliance, even though the actual policy statements lack target, direction and urgency.
Command and Control in a Nuclear-Armed Iran
In the long standoff regarding its nuclear ambition, Iran has cultivated ambiguity and been loath to reliably assure the international community of its ultimate intentions, complicating Western efforts to understand, let alone constrain, Tehran’s endeavors.
Ballistic Missile Defense in Japan: Deterrence and Military Transformation
In December 2003, Japan decided to be the second country in the Asia-Pacific to deploy a ballistic missile defense (BMD) system.
Deterring the Weak: Problems and Prospects
Strong states often fail to deter vastly weaker competitors. This paper explores some reasons of this failure and identifies factors that can increase the prospects that deterrence will succeed in these situations.
To Attack or Not to Attack: Israel Confronts a Dramatic Decision
In the heat of the public discussion on the possibility of an Israeli attack on Iran’s nuclear facilities, Prime Minister Benjamin Netanyahu stressed that he has not yet decided whether to attack Iran. At the same time, partly in response to opponents of such an attack, he made it clear that the risk of harm to the home front at this point, when Iran still does not have nuclear weapons, is dwarfed by the risks involved in an attack on Israel after Iran has gone nuclear.
