In siding with Russia at the UN, the US has laid bare the extent of the shift. Bilateral visits cannot disguise the underlying crisis

The rumblings prompted by Donald Trump’s re-election soon gathered force. First came tariffs and threats of territorial annexation; then the greater shocks of JD Vance’s Valentine’s Day massacre of European values and Mr Trump’s enthusiastic amplification of Kremlin lines on Ukraine.

On Monday came another seismic moment. For more than a decade, the UN security council has been largely paralysed by the split between the five permanent members – Russia and China on one side; the US, France and Britain on the other. This time, when the US brought a resolution calling for an end to the war in Ukraine on the third anniversary of Russia’s invasion, it did not criticise Moscow, demand its withdrawal or back Ukraine’s sovereignty and territorial integrity. The result was that China and Russia backed the resolution – while the UK and France, having failed to temper it, abstained.
