Cuaderno de Estrategia 229-B. Strategy Notebook 229-B Global Nuclear Panorama

This Strategy Notebook, devoted to the analysis of the global nuclear panorama, is both derived from and continues the 2020 publication titled Non-Proliferation and Nuclear Arms Control at a Crossroads (Strategy Notebook No. 205), and seeks to update, assess and conduct an in-depth study of the changes to the international nuclear architecture in recent years, highlighting new power dynamics, the evolution of the nuclear strategies of major powers, and the current state of international forums, treaties and
initiatives that make up the nuclear non-proliferation regime1. A regime that, despite being more than six decades old (its cornerstone, the Nuclear Non-Proliferation Treaty or NPT, entered into force in 1970) and the crisis of obsolescence in recent years, is still fully valid and in effect.
