The Guardian view on Putin’s nuclear threats: Russia is losing in Ukraine | Editorial

With 2,000 tactical warheads at his disposal, we must hope the Russian president's warnings are tactical

As the war in Ukraine and its consequences weaken Russia's conventional military, Vladimir Putin's government has resorted to nuclear threats designed to project strength. Mr Putin wants to intimidate his opponents. But his strategy is failing. Instead of Ukraine's allies backing down, they are stepping up their support. The US Congress this week approved $11bn of arms to Ukraine, three times the total military aid Washington has so far given.

The US president, Joe Biden, was right to call out Mr Putin for making idle comments" about nuclear weapons. It is unthinkable that blunders and miscalculations would take the world to the edge of the nuclear abyss. Yet that is where the world is heading. Whereas the Cuban missile crisis lasted 13 days, Russia's war is already into its third month. With no clear end in sight, more deadly battles look inevitable - increasing the chances of mistakes.
