A US security blunder, in which a journalist was added to a supposedly top secret chat group of senior White House officials, speaks volumes to the outside world about how the Trump administration works – but perhaps most notably that what JD Vance, Pete Hegseth and others say in public, they say in private too.
Friends and foes alike will not have failed to notice the contempt expressed by Vance for Europe in the leaked messages. It will merely confirm suspicions that the US leadership can no longer be trusted, and the instinct now for many countries must be to try to forge away from the old ally.
Could Europe really go it alone without America? The stream of insults, tariffs, threatened land grabs and the US distancing from Nato are are one thing. But in terms of culture, economics, diplomatic affairs and defence, how straightforward would it be to decouple – and would the outcomes really be for the better?
Emma Graham-Harrison, Vanessa Thorpe and Phillip Inman weigh up the pros and cons of unravelling the ties that bind Europe to America. And from Washington, Andrew Roth examines how the White House leak reveals the depths of the Trump administration’s loathing of Europe.
