In a report published on Friday, 2026.03.27, the British parliament’s Joint Committee on the National Security Strategy (JCNSS) said the UK government should prepare for a “worst-case scenario” in which Europe could no longer rely on US support in a crisis.
The report warned, “The UK must be prepared to take on more of the cost for its and Europe’s security through investing in partnerships and multilateral dialogues with other ‘middle powers’, for example Canada, Australia and India, to avoid being squeezed by great power competition between the United States and China.”
The UK currently relies on the US in several key national security areas, including maintenance of its Trident nuclear missiles, intelligence sharing, and major projects such as the F-35 fighter jet and Aukus submarine deal with Australia.
