The threat of Russia using nuclear weapons in Ukraine is “real” and “absolutely irresponsible”, according to the US president, Joe Biden. He was reacting to questioning from journalists as to whether he believed Belarus had been taking delivery of Russian tactical nuclear weapons.
If true, it’s the first time Russia has deployed nuclear warheads outside its borders since the end of the cold war. This does not immediately mean a nuclear escalation with Nato, since Russian nuclear missiles stationed in the Kaliningrad region already put Poland and the Baltic states within range. Experts are sceptical about Russia’s intentions to use these weapons in Ukraine.
But the presence of tactical nuclear arms in Belarus has, nevertheless, important implications for European security.
