France's President Emmanuel Macron delivers a speech next to nuclear-powered ballistic missile submarine (SSBN) submarine "Le Temeraire" – S617 during his visit to the Nuclear Submarine Navy Base of Ile Longue in Crozon, north-western France on March 2, 2026. High expectations, few certainties: on March 2, 2026, Emmanuel Macron is set to outline how France's nuclear deterrent can help strengthen security in Europe in the face of a increasingly brutal world and an increasingly uncertain US ally. This issue has been brought sharply into focus by the Israeli-US offensive in Iran this weekend, against the backdrop of the Iranian nuclear crisis, which is shaking the entire Middle East and, by extension, the international community.
