General Sir Nick Carter addressed the Royal United Services Institute in London (Image: Royal United Services Institute/PA Wire) “Deterring these threats, signalling to the Russian regime that we shall not tamely acquiesce should they escalate, requires conventional hard power – warships and aircraft – as well as less conventional capabilities like cyber. “And it requires us to hold their backyard at risk whether that’s in the Barents Sea, the High North, the Baltic or the Black Sea.” Sir Nick then told RUSI that China is playing the “Digital Great Game” and cited its BeiDou satellite navi-gation system – a version of GPS. He said it provides more accurate coverage than GPS in 165 of 195 capital cities around the world.
