Can France’s Nuclear Deterrent Be Extended to Europe?
The Trump administration’s hostile rhetoric towards Europe, its seeming reluctance to uphold the United States’ (US) security guarantees, and Russia’s assertive behaviour on the international stage have led to a profound strategic debate on nuclear deterrence amongst Europeans. Some European leaders have questioned whether France could fill the nuclear deterrence gap left by the US, and Emmanuel Macron has initiated a strategic debate to this end. Extending the French nuclear deterrent to protect Europe will require it to be complemented by the United Kingdom’s (UK) own deterrent. It is a process that necessitates careful consulting between European allies, as well as an appropriate framework and doctrine in order to be effective. The question will also be whether France’s nuclear deterrent must complement or replace the US’. For European land forces, this shift signals a closer strategic alignment between European NATO allies and will influence the likeliness of high-intensity conflict in the future.
