President Emmanuel Macron is expected to deliver a speech on Monday at the Île Longue base, aiming to update France's nuclear doctrine in light of the evolving geopolitical landscape. This update comes four years after the onset of the war in Ukraine and just days following recent military actions by the U.S. and Israel against Iran. Macron's address is significant as it marks an important moment for France's nuclear strategy, particularly considering the component of France's nuclear deterrent that includes submarine-launched ballistic missiles which are currently on patrol at sea.

The emphasis of Macron's speech will likely be on reinforcing France's nuclear capabilities as part of European security. The strategic underpinning of both sea-based and air-based nuclear capabilities seeks to address potential threats and reassure allies about France's commitment to a robust deterrent posture. In a context where global security is increasingly unpredictable, Macron's update to the nuclear doctrine serves not only to respond to external threats but also to foster a narrative of collective European defense.

As Macron approaches the end of his presidential term, this address serves dual purposes: to reaffirm France's position in the realm of nuclear deterrence and to highlight the importance of solidarity among European nations in the face of external challenges. By framing his speech within the context of European security, Macron aims to underline the role of nuclear deterrence as a pivotal element of strategic defense for Europe in a rapidly changing world.
