Nuclear and Strategy Network - New Generation
The Nuclear and Strategy Network – New Generation was created in September 2015. This network is intended for students (Master 2 level, doctoral students, doctors) and young professionals (diplomats, engineers, journalists, etc.) interested in deepening their knowledge on military nuclear issues, in particular deterrence and non-proliferation.
The Network is administered by the Foundation for Strategic Research (FRS) and the French Institute of International Relations (Ifri), with the support of the French government.

French Forward Deterrence: What Is in It for the Baltic States?
For what may be its most significant stress test since the end of the Cold War, European deterrence is under strain. Russia’s war against Ukraine has demonstrated Moscow’s willingness to use force and its ability to combine conventional operations with nuclear signalling, coercive rhetoric, and hybrid actions. At the same time, the gradual deterioration of transatlantic relations has revived concerns about the reliability of extended deterrence.
Taking the Pulse: Is France’s New Nuclear Doctrine Ambitious Enough?
French President Emmanuel Macron has unveiled his country’s new nuclear doctrine. Are the changes he has made enough to reassure France’s European partners in the current geopolitical context?
Macron Offers a Promising Vision for Nuclear Deterrence in Europe
Macron’s concept of ‘forward deterrence’ offers a distinctly European approach to nuclear deterrence.
France has a new nuclear doctrine of ‘forward deterrence’ for Europe. What does it mean?
On Monday, French President Emmanuel Macron delivered a speech on France’s nuclear deterrence at the Île Longue naval base near Brest in Brittany, which hosts the country’s nuclear-armed ballistic missile submarines. Such addresses are a well-established presidential ritual, typically delivered once per presidential term and receiving moderate attention. This one, however, was highly anticipated in France and abroad, given the profound geopolitical shifts since Macron’s first nuclear speech in February 2020.
Mind the Deterrence Gap: Assessing Europe’s Nuclear Options
Europe must urgently confront a new nuclear reality. In recent years, Russia’s nuclear-backed revisionism has reintroduced nuclear coercion and the threat of nuclear escalation to the continent, underscoring the importance of credible nuclear deterrence. At the same time, Europe’s traditional reliance on US extended nuclear deterrence appears politically more fragile than at any point since the Cold War. Together, these developments require Europeans to think about their nuclear options.
Saudi Arabia’s Nuclear Temptations. Lessons Learned from Regional Instability
Saudi Arabia’s integration in the international arena and regional stability, notably through reducing its dependence on fossil energies, are crucial elements for the success of the Kingdom’s Vision 2030, the Crown Prince’s top priority. However, Mohammed bin Salman’s declarations in 2018 and 2021, indicating that “if Iran develops a nuclear bomb, we will follow suit as soon as possible”, combined with the recent strikes on key Iranian nuclear facilities, do not bode well for the future of the Kingdom, the region and the non-proliferation regime at large.
How should Britain and France cooperate to realise the Northwood Declaration?
During his state visit to the United Kingdom (UK) last week, Emmanuel Macron, President of France, signed a joint declaration with Sir Keir Starmer, Prime Minister, on nuclear cooperation between Britain and France. The Northwood Declaration highlights that while both countries’ nuclear arsenals remain sovereign, cooperation on nuclear deterrence can ‘contribute significantly’ to the security of the North Atlantic Treaty Organisation (NATO) and the Euro-Atlantic region.

How has the Iranian strategic discourse about nuclear weapons and deterrence evolved?
A Fragile Consensus? The Pressure on the Norm Against Nuclear Testing
Apart from North Korea, no state has conducted explosive nuclear tests in the 21st century, reflecting the emergence of a strong international norm against such testing.
Taking the Pulse: Can Europeans Build Their Independent Extended Nuclear Deterrent?
Confronted with a U.S. disengagement and the Russian threat, Europeans are reconsidering their stance on nuclear deterrence. Given the capabilities of the French and British arsenals, can Europe develop an independent nuclear deterrent?
