Last month, Air Chief Marshal Sir Richard Knighton, Chief of the Defence Staff, delivered a lecture at the Royal United Services Institute in which he warned that Russia was developing new and destabilising weapons systems. Arguing that the current Russian leadership’s aim was to “ultimately destroy NATO”, he proposed that UK defence must be the “central organising principle of government”. He urged that: “Sons and daughters. Colleagues. Veterans … will all have a part to play. To build. To serve. And if necessary, to fight. And more families will know what sacrifice for our nation means”.
