Some politicians seem comfortable with the prospect of a new cold war. They shouldn’t be | Christopher S Chivvis

Republican leaders draw on Reagan-era nostalgia to unite their party, but a 21st-century cold war would not end well for anyone

Events surrounding the first year anniversary of the Russian invasion of Ukraine have had a cold war-esque feel, with America and its allies lined up on one side and China and Russia on the other. Some politicians in Washington - and perhaps Beijing - seem comfortable with this. But they should be careful. There's no reason to believe a cold war re-run in the 21st century would turn out well for anyone, above all the US.

This past week, President Biden paid a dramatic visit to Kyiv and then addressed a crowd in Warsaw, pledging unwavering US support for Ukraine. President Putin gave a speech of his own in which he stubbornly insisted that Nato was to blame for the war and suspended Russia's participation in a vital nuclear arms control treaty. The US secretary of state, Antony Blinken, meanwhile confronted his Chinese counterpart, Wang Yi, in Munich, warning China not to supply Russia with weapons. Yi then flew to Moscow and stood alongside President Putin for a photo opportunity.
