Britain must rethink its reliance on a volatile America and private tech giants in a world where infrastructure is weaponised

With the prime minister’s Churchillian claims that “the front line is here”, the public might expect a military posture that meets the drama of the moment. Yet the promised rise in defence spending – from 2.3% to 2.5% of gross domestic product by 2027 – suggests something less than full-scale mobilisation. The strategic defence review is systematic and detailed, but it remains an exercise in tightly bounded ambition. It speaks of daily cyber-attacks and undersea sabotage, but proposes no systemic institutional overhaul or acute surge in resilience. Given the developing dangers, it is surprising not to spell out a robust home-front framework.

Instead, it is a cautious budget hike in the costume of crisis – signalling emergency while deferring real commitment for military financing. The review suggests that the more ambitious spending target of 3% of GDP, still shy of Nato’s 3.5% goal, is delayed to the next parliament. The plan is not to revive Keynesianism in fatigues. It is a post-austerity military modernisation that is technocratic and geopolitically anxious. It borrows the urgency of the past without inheriting its economic boldness.
