Ukraine is the biggest and most consequential of all the American betrayals | Simon Tisdall

As the war enters its fifth year, it’s time for Europe to take the fight to Putin on its own terms and tell Trump to get lost

Viewed from Europe, the US’s failure to defend the people of Ukraine against Russian aggression is the greatest and most consequential of a host of recent American betrayals. It’s not just the sickening subservience shown to Vladimir Putin, an indicted war criminal and mass killer. It’s not only the victim-blaming and bullying of Kyiv into making concessions. It’s not even Donald Trump’s crass attempts to monetise the war and milk the misery of millions for Nobel glory, while undercutting Nato allies and trampling sovereign rights.

What really shocks, and hurts, is the sheer bad faith shown by a country that Europeans always counted a friend. As the 18th-century English gothic novelist Ann Radcliffe noted, “few circumstances are more afflicting than a discovery of perfidy in those whom we have trusted”. To echo Trump’s dark warning after he was rebuffed over Greenland: Europe will remember.
