Europe must now tell Trump that enough is enough – and cut all ties with the US | Alexander Hurst

How do you retain a space of democracy in a world that is reverting to violent conquest? By building a protective moat of federalism around it

He keeps encouraging me ... to choose between Europe and the US. That would be a strategic mistake for our country," Keir Starmer said in response to Ed Davey's question in the House of Commons last week, about whether a US move against Greenland would mean the end of Nato.

What about Europe, though? As Danish and Greenlandic ministers prepared to face JD Vance in the White House, the question was would Europe finally choose between Europe and the US? Will its leaders have the courage to tell the full truth - that the US isn't simply abandoning its allies and destroying the international order but is now in the position of active and hostile predation by force - and more importantly, to act on it? To offer Denmark moral and material backing, and Greenland a future of self-determination and membership, rather than subservience to US resource plunder?

Donald Trump has already set the tone by saying the US will seize Greenland one way or the other", and no part of the triumvirate around him is trying to hide their imperial intentions any more. Not the nepotists and grifters amassing ever greater private fortunes. Not the white supremacist ideologues drawing inspiration from Ein Volk, Ein Reich, Ein Fuhrer! to post One Homeland. One People. One Heritage", via official US government social media accounts. Not the techno-nihilists salivating to mine every bit of Greenland's mineral resources and rule their own neofeudal city states on its coast.

When Trump says that the only constraint on his exercise of power is my own morality", that means there is no constraint. Like Vladimir Putin, he will keep grabbing until someone imposes a limit on him.
