The western allies would provide weapons and aid to Kyiv, impose sweeping economic and financial sanctions on Moscow and reduce the rouble to “rubble”, Biden vowed. Though not a Nato member, the US would help Ukraine win this symbolic battle for freedom and democracy. But it would not directly confront Russia unless Russia first attacked Nato.

Thirty months on, Biden’s containment strategy is failing miserably. Like an untreated cancer, Ukraine’s crisis metastasises uncontrollably. Far from being confined to the mud and ice of the Donbas, the war’s spreading, toxic fallout grows more globally destructive by the day. It contaminates and blights everything it touches.
