The parallel drawn between the ambitions of Mr Xi’s China and that of the former Soviet Union is equally misleading. The cold war was a struggle between competing systems. Today’s Sino-American rivalry is a contest between states.

The Chinese regime has grand ambitions. It wants to push the US out of the western Pacific and establish its own hegemony in east Asia. It is a fair assessment that the long-term goal is to replace the US as the world’s most powerful nation. But, to borrow from Kennan’s characterisation of Soviet aims, Beijing is not seeking the defeat of capitalism across the world.

Moscow presented the world with an alternative way of ordering society. It had fellow travellers, allies and agents in established parties across the world. This was a contest that only one side could survive. Beijing thinks in terms of “spheres of influence”. Mr Xi is not anticipating what Mr Pompeo calls the “global hegemony of Chinese communism”.

This is not to deny the obvious clash of ideologies. On that score, however, Mr Pompeo’s rallying cry for freedom is scarcely helped by Mr Trump’s frequent public applause for unpleasant autocratic regimes, including that of Mr Xi. By the account of his former national security adviser John Bolton, the president offered personal backing to Mr Xi for the brutal crackdown against Muslim Uighurs in Xinjiang province.
