UK may ‘step into the breach’ and shield EU ally from Russia as US commitment weakens

Jennifer Kavanagh, Senior Fellow & Director of Military Analysis at the US-based Defense Priorities think tank, said that the UK is well-positioned to play a pivotal role in Europe’s nuclear deterrence. She added: “The UK has the capability and political will to extend its nuclear protection beyond its own borders. In the wake of US hesitations, the UK could step into the breach, ensuring Germany is shielded from Russian nuclear coercion.” Ms Kavanagh, speaking before Friday’s extraordinary clash between Mr Trump and Ukrainian President Volodymyr Zelensky, emphasised the strategic importance of the UK’s nuclear submarines and air force.
Despite these challenges, Kavanagh emphasised that Europe cannot afford to rely solely on the US for its nuclear deterrence. She concluded: “If the UK and France can ensure that their nuclear umbrella remains credible, it would enhance Europe’s long-term security and diminish its dependency on the US.
