In November 2019, from the salon doré of the Élysée Palace, where Charles de Gaulle once held court, Emmanuel Macron warned his fellow Europeans that Nato, the transatlantic alliance that had secured Europe since 1949, was on the point of “brain death”. President Donald Trump’s administration, to the horror of America’s own soldiers, had just unilaterally withdrawn support from the Kurdish forces in northern Syria, sacrificing them to Bashar al-Assad and Recep Tayyip Erdoğan. Within a year, the US would impose sanctions on Turkey, a member of Nato since 1952, for its purchase of Russian anti-aircraft missiles. Disunity reigned.
In 2017 Angela Merkel had returned from a chaotic meeting with Trump to declare that Europe could clearly no longer count on America as an ally and must look to its own resources for its security. Macron’s concern over two years later was that little had happened to make good on that realisation.
