On 10 April 2026, Sky News reported that the UK is quietly updating its Government War Book — a Cold War-era blueprint for transitioning the entire nation to a war footing. Air Chief Marshal Sir Richard Knighton, Chief of the Defence Staff, confirmed that the Cabinet Office is coordinating across government departments, police, hospitals, industry, and critical infrastructure to prepare for potential conflict. The plan includes measures such as shutting schools, clearing hospital beds, rationing food and fuel, protecting national treasures, and educating the public on resilience and their role in supporting the armed forces.
This is not abstract planning. It revives old contingency thinking for a "modern context" with modern infrastructure, while emphasising resilience against hybrid threats and actions "above the threshold of war." Knighton stressed that renewing water, electricity, and transport systems must now factor in adversary sabotage, not just natural disasters. Defence spending is promised to rise to 3.5% of GDP by 2035 (from just over 2%), and a delayed 10-year Defence Investment Plan is still awaited.
On paper, it sounds serious. In reality, it raises uncomfortable questions: with what army? And against whom?
A Hollowed-Out Fighting Force
The British Army is currently around 73,000 regular soldiers — its smallest size in centuries. Recruitment and retention have been chronic problems for over 15 years. Reservists add roughly 30,000, but ambitious targets to grow the total force (regular + reserve) to 100,000+ remain aspirational and largely unfunded in the near term.
Decades of post-Cold War peace dividend, outsourcing, and budget squeezes have left the military under-equipped and over-stretched. The Strategic Defence Review 2025 talked about making the Army "10x more lethal" through technology, drones, AI, and swarms — a "20/40/40" mix of traditional platforms, expendable munitions, and reusable autonomous systems. Yet the hard numbers tell a different story: slow recruitment, delayed procurement, and an industrial base that has atrophied.
The government speaks of putting the forces "back on a war footing," but the timeline is glacial. Major spending increases are pushed out to 2035. Industry waits in limbo for clear funding signals. A separate Sky News investigation described the broader push to transform the military as a "fiasco," with too much focus on bureaucratic restructuring and not enough on immediate readiness.
In short, the UK is dusting off grand war plans while its actual warfighting capacity remains historically weak. Talk of national mobilisation and civilian resilience feels premature when the professional core is still struggling to hit basic headcount targets.
Who Exactly Are We Preparing to Fight?
The threats are real: Russia's war in Ukraine, hybrid actions (including the "shadow fleet"), rising tensions with China, instability in the Middle East (including the current Hormuz crisis), and general great-power competition. Knighton referenced the need to "relearn lessons of the Cold War."
Yet the rhetoric often stays vague. Is the primary scenario a European land war supporting NATO against Russia? A naval/air conflict in the Indo-Pacific alongside the US and allies? Or something closer to home — protecting critical infrastructure from sabotage?
The satirical edge writes itself: with an army smaller than many police forces and recruitment woes persisting, one wonders if the contingency plans include scenarios against Antarctica. Penguins don't recruit well either, but at least the logistics might be simpler than sustaining high-intensity operations thousands of miles away while simultaneously guarding the home front!
The uncomfortable truth is that Britain's political class spent 30+ years assuming large-scale conventional war in Europe was a relic of the past. Now, faced with multiple credible threats, the response is long-term planning documents, percentage-of-GDP promises years away, and calls for the public to "think differently about resilience."
Echoes of Ignored Warnings
This fits the broader pattern we've seen across 2026: monetary fragility, supply-chain chokepoints (Hormuz), cultural tensions, unresolved COVID origins, and eroding trust in institutions. Elites often sleepwalk through decades of under-investment and ideological choices (de-industrialisation, Net Zero constraints on energy, outsourcing), only to panic-plan when the bill comes due.
A revived War Book is better than nothing. But without rapid, realistic growth in manpower, munitions stockpiles, industrial capacity, and public buy-in, it risks becoming performative theatre. True national resilience requires hard choices: reversing recruitment collapse, rebuilding the defence industrial base, prioritising energy security, and being honest about which threats matter most and what trade-offs society is willing to accept.
Until then, the gap between ambitious war planning and actual fighting power remains wide. Preparing the nation for war is prudent. Doing so with a hollowed-out force and vague threat assessments risks turning serious strategy into expensive signalling.
Britain should prepare seriously — but the public deserves clarity on both the "with what" and the "against whom." Penguins, fortunately, are not yet on the list.
