"It is clear that the US can no longer be regarded as a reliable ally for the Europeans. But the Trump administration’s political ambitions for Europe mean that, for now, America is also an adversary — threatening democracy in Europe and even European territory, in the case of Greenland.
So what to do? Europeans need to start preparing fast for the day when the US security guarantee to Europe is definitively removed. That must involve building up autonomous defence industries. It should also mean a European mutual defence pact, outside Nato, that extends beyond the EU — to include Britain, Norway and others.
Trump will use any leverage he has to force America’s European allies into compliance on issues from trade and security to their domestic politics. That means that Europe must now start the painful process of “de-risking” its relationship with the US, looking for areas of dangerous dependence on America and stripping them out of the system.
Entrusting critical infrastructure to Musk would create a huge new vulnerability. The Trump administration will also put enormous pressure on Europeans to buy more American weaponry. Under current circumstances that would be folly."
