French President Emmanuel Macron will deliver a highly anticipated speech on Monday about the contribution of French nuclear deterrence to European security amid geopolitical turmoil and questions about the US nuclear umbrella. This speech will follow up on his address on February 7, 2020, in which Macron proposed that Europeans rethink their nuclear strategy. A source close to Macron indicated that "there will undoubtedly be some important transformations and developments," without providing further details. The source also noted that "this will be a key moment in the (presidential) term." Macron will speak at the "Île Longue" base in Brest (west), where the four nuclear submarines ensuring French nuclear deterrence in the oceans are stationed, alongside the strategic air forces.
