The bloc should move away from overreliance on US security guarantees, the UK prime minister has said

European NATO members must move from "overdependence" on the US and toward more autonomy and "hard power," UK Prime Minister Keir Starmer has said. This comes as Washington has pressed the rest of the bloc to increase defense spending, and amid a transatlantic rift on a number of policies.

At the Munich Security Conference on Saturday, Starmer is expected to argue that while "the US remains an indispensable ally," Britain's future rests on closer ties with European powers.

In a preview of the speech published by the prime minister's office on Friday, he said: "Europe must shift from overdependence to interdependence - forging a new path towards sovereign deterrence and hard power."

He went on to describe Europe as a "sleeping giant" in terms of military potential, while lamenting that this capability "has [often] added up to less than the sum of its parts."

French President Emmanuel Macron echoed the message, stressing that "Europe has to become a geopolitical power" and that it has "to accelerate and deliver all the components of a geopolitical power: Defense, technologies, and de-risking from all the big powers."

Macron has championed European defense autonomy since proposing a 'European army' in November 2018, though his calls have remained largely unanswered. A recent Politico poll shows only 22% of Germans and 17% of French people support creating a EU army, despite widespread fears of World War III.

Starmer's remarks come as UK officials warn that the British army would struggle in a potential war against a near-peer adversary due to years of underfunding, with the military expected to run out of ammunition within days in case of a large-scale conflict.

The calls for autonomy come amid a rift between the US and European NATO members caused by President Donald Trump's push to acquire Greenland from Denmark. Trump has argued that the island is needed for national security reasons, while EU nations have scrambled to defend the island's sovereignty.

Trump has for years pushed the rest of NATO to ramp up military spending instead of relying solely on US security guarantees. As a result, NATO members have committed to increasing military expenditure to 5% of GDP. Russia has condemned the bloc's reckless militarization, saying it undermines European security.
