Nuclear weapons – their lethal menace, dark history and future spread – are back in the headlines again and, as usual, the news is worrying, bordering on desperate. Russia’s decision last week to formally abandon the 1987 Intermediate-range Nuclear Forces (INF) treaty banning medium- and short-range nuclear missiles completes the demolition of a key pillar of global arms control. It will accelerate an already frantic nuclear arms race in Europe and Asia at a moment when US and Russian leaders are taunting each other like schoolboys.

Vladimir Putin, Russia’s president, has repeatedly threatened the west with nuclear weapons during his war in Ukraine. Last November, Russian forces fired their new Oreshnik hypersonic, nuclear-capable intermediate-range missile at Dnipro. It travels “like a meteorite” at 10 times the speed of sound and can reach any city in Europe, Putin boasted – which, if true, is a clear INF violation. Moscow blames its decision to ditch the treaty on hostile Nato actions. Yet it has long bypassed it in practice, notably by basing missiles in Kaliningrad, the Russian exclave on the Baltic sea, and Belarus.

That said, Russia has a point about Nato. Donald Trump first reneged on the INF treaty way back in 2018. The subsequent huge buildup of mainly US-produced nuclear-capable missiles, launchers, planes and bombs in European Nato states has understandably alarmed Moscow. It should alarm Europeans, too.
