The UK and its Nato allies must upgrade their military capabilities if the coalition of the willing in Ukraine is to be a successful deterrence against Vladimir Putin, a former military chief has warned.
In a damning report for the Policy Exchange think tank, Sir Jock Stirrup, a former Royal Air Force commander and chief of defence staff, said the UK has been hamstrung by an “outdated nuclear doctrine” and needs to recognise that deterrence relies “on a spectrum of capabilities, not just nuclear weapons themselves”.
