A Call for European Nuclear Cooperation

Former British diplomat David Mening advocates for a shift away from reliance on US nuclear weapons, suggesting closer collaboration between Britain and France. Mening argues that growing uncertainty surrounding American reliability could leave Europe exposed to potential Russian aggression. This perspective highlights the strategic imperative for bolstering European defense capabilities through enhanced cooperation.
