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.

Corps analyses

On the contrary, the historical record shows that the text of the NPT was crafted by the US and the USSR, in close cooperation, precisely so that NATO's arrangements would be compatible with Treaty obligations – while also constraining the ability of non-nuclear states to acquire nuclear weapons. This paper shows how the US and USSR negotiated Articles I and II – the critical parts of the NPT pertaining to nuclear weapons proliferation. The US explored multiple options and sought to balance several (sometimes conflicting) objectives during these negotiations, from managing its key bilateral relationships (particularly with the USSR and West Germany), to strengthening NATO's defensive capacity and credibility, and, finally, to preventing the further spread of nuclear weapons. Ultimately, the NPT proved successful because the final text proved satisfactory to alleviate the concerns of all parties involved – the superpowers, NATO, the Warsaw Pact and the neutral non-aligned countries.

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.

Multiple Launch Rocket Systems Europe’s Long-standing and Enduring Dependence?

Date de publication

Accroche

The war in Ukraine has underlined the importance of multiple launch rocket systems (MLRS) in modern conflict, especially a war without clear air superiority and hence a reduced potential for air-launched deep strike. In 2022, the European MLRS fleet was split between a variety of Western platforms developed at the end of the Cold War and specialized in precision strikes.

Autonomous Systems in the Underwater Domain: A Limitless Revolution?

Date de publication

Accroche

One of the decisive strategic factors in the ongoing Russo-Ukrainian war is the mass use of aerial, maritime, and terrestrial autonomous capabilities, which are transforming the face of the battlefield. Nevertheless, many of these drones are still remotely piloted, operated, or supervised, testifying to the fact that the autonomization of military capabilities is still at an embryonic stage.
