UK Prime Minister Keir Starmer and French President Emmanuel Macron announce stepped-up nuclear cooperation in the face of Russian threats

The announcement by the British and French leaders underlines an unprecedented nuclear partnership, given the uncertainties over the US commitment to Europe's defense. The agreement allows coordination of both countries' nuclear deterrents, ensuring a joint response to external threats. The UK is modernizing its nuclear capabilities, including through the purchase of F-35A jets, while France maintains an independent nuclear doctrine. Macron stressed the shared responsibility of the two nations for Europe's security.
