The mood in the Government this week is decidedly grim, and it isn’t just because of the usual internal bickering, the prospect of difficult elections or the stalled economy. A missile has just been fired into the heart of Downing Street by some of the most respected names in British security.
Lord Robertson, the former NATO Secretary-General and a man not known for hyperbole, has launched a blistering critique of Sir Keir Starmers government’s approach to defence, accusing the current leadership of a “corrosive complacency” that threatens the very fabric of national safety.
As the conflict involving Iran continues to destabilise the global order, war rages in Europe, and Russia continues to flex its muscles in the seas around the UK, the gap between the government’s rhetoric and the reality of the UK’s depleted military is becoming impossible to ignore.
Lord Robertson’s intervention is particularly stinging because it comes from within the traditional Labour establishment. He has argued that the government is sleepwalking into danger. According to Robertson, “There is a corrosive complacency today in Britain’s political leadership.”
He says ministers have failed to grasp the urgency of the moment: “Lip service is paid to the risks, the threats, the bright red signals of danger – but even a promised national conversation about defence can’t be started,” he warned.
The heart of the issue is money. The Ministry of Defence is staring at a £28 billion funding gap that threatens to sink the government’s ten-year defence investment plan before it gets going. While the Prime Minister has spoken of “ironclad” commitments, delivery has been delayed, leaving the armed forces in limbo, under-resourced, ill-equipped, and unable to meet all its commitments.
Insiders describe a power struggle between the military leadership and the “non-military experts in the Treasury”, with those officials accused of “vandalism” by critics who say bean-counting is being put ahead of national security.
This friction with the Treasury sits behind Lord Robertson’s most controversial claim: that the UK is prioritising its social security bill over its physical survival. As he put it, “We cannot defend Britain with an ever-expanding welfare budget.” Robertson’s verdict is blunt: “We are underprepared. We are under-insured. We are under attack. We are not safe… Britain’s national security and safety is in peril.”
The state of the military backs up those warnings. Sir Richard Barrons, the former Commander of Joint Forces Command, has described the British military as “too small and too undernourished.” That concern is echoed in Washington. Donald Trump dismissed the Royal Navy’s aircraft carriers as “toys”, while Pete Hegseth, the US Secretary of Defence, sarcastically mocked the “big, bad Royal Navy” over its limited role in protecting shipping routes during the Iran crisis. The jibes are crude, but they have landed because they reflect a real argument about whether Britain still has the depth to sustain serious military operations.
Those anxieties have been sharpened by HMS Dragon. The destroyer, sent east as tensions mounted, took three weeks to reach the Mediterranean, only to return to port because of water supply issues. In the middle of a regional crisis, it looked like a symbol of a wider problem: too few ships, stretched deployments and too little resilience when something goes wrong. When a frontline warship cannot stay on station after a lengthy transit, warnings about readiness stop sounding abstract.
The geopolitical context makes these failings even more dangerous and pointed.
The ongoing wars in Iran and Ukraine have shown that modern conflict is no longer a distant scenario and that it involves cyber-attacks, supply chain disruption, threats to commercial shipping, energy security and the possibility of rapid escalation across several theatres at once.
Britain’s weaknesses are therefore being judged against live crises in which allies expect speed, endurance and credible force projection. Yet the UK’s ten-year investment plan remains a draft in a drawer, after being delayed yet again, with critics denouncing Starmer as “ditherer”, a leader in name only, who can’t get tough decisions through Cabinet and match defence rhetoric with the resources it needs.
Ultimately, the warnings from Robertson and Barrons suggest that the government is operating on a version of reality that no longer exists. They argue that the luxury of time has evaporated. If the Treasury continues its perceived “vandalism” of the defence budget, the “corrosive complacency” Starmer is accused of could become his defining legacy.
The message from Westminster’s defence heavyweights is clear: a country that cannot defend itself eventually finds that it has very little left to govern. The time for lip service has passed; the “bright red signals of danger” are flashing, and they are impossible to ignore.
