Introduction

The UK’s ability to act ethically on the world stage depends on something more fundamental than diplomacy or political will: sovereign capability. A nation that cannot defend itself, sustain itself, or protect its population cannot meaningfully choose its own principles. It is forced to choose the preferences of whichever partner it depends on most. Recent geopolitical events have exposed how fragile that autonomy has become.

The escalation involving the US, Israel, and Iran has raised profound questions about the global norm against wars of aggression – the same norm Russia violated in Ukraine. At the same time, political vulnerabilities inside Europe present opportunities for adversaries to fracture alliances without firing a shot. These dynamics converge on a single truth: without resilience, the UK cannot act from principle. It can only react from dependency.

The Principle at Stake: Aggression Is Illegitimate

Russia’s invasion of Ukraine was a clear violation of one of the last lines in international order: that wars of aggression are unacceptable. This principle underpins deterrence, alliance cohesion, and the legitimacy of collective defence.

When Western allies appear to blur that line – even against regimes that are undeniably dangerous – the moral clarity that underpins deterrence begins to dissolve. Perception matters as much as reality. If aggression becomes a blunt tool used by all sides, the norm itself weakens, and adversaries take note.

Timing, Triggers, and Strategic Context

The Iranian regime has long been dangerous. Many would argue it should have been confronted years ago. But the current escalation – without a convincing trigger, without a coherent plan for the aftermath, and while Russia continues its war in Europe – is strategically dangerous.

The UK was right to avoid joining the initial strikes, especially given how vulnerable our own capabilities have become. Yet it may still have been necessary to allow allies to use UK bases, even if we did not participate directly – not because we agreed with the strikes, but because we have allowed ourselves to become so exposed that damaging a now‑tenuous but strategically essential alliance over a regime that is, ultimately, an adversary to us as well, would have been reckless. This is the uncomfortable reality of diminished capability: decisions are shaped by weakness, not strategy.

The UK’s Dilemma: Acting from Dependency, Not Principle

For decades, UK defence capability has been hollowed out. Resilience systems – food, energy, manufacturing, civil protection – have been neglected. Strategic dependency on the US has grown at the very moment US behaviour has become less predictable.

This leaves the UK in a tricky position when calibrating its involvement in global events. Decisions are shaped not only by principle, but by vulnerability. Avoiding direct involvement in the Iran strikes was a principled decision – and, in my view, the right one. But the strategic cost of taking that principled stance was higher than it should have been. Our diminished capability means we have far less room to manoeuvre, and far less ability to absorb friction with key allies when our values diverge. In a healthier strategic position, the UK could have upheld its principles without risking strain on an already fragile alliance.

This dependency also weakens an essential part of alliance dynamics: the ability to push back. Healthy alliances rely on honest friction. When partners can challenge one another, it helps major powers calibrate their foreign policy and avoid strategic overreach. But the UK’s current vulnerability makes such pushback costly. Silence becomes the safer option, even when decisions taken by allies undermine the very norms we claim to defend. Dependency does not only limit our choices; it limits our voice.

The Erosion of Deterrence

If the norm against aggression weakens, the consequences ripple far beyond the Middle East. Deterrence relies on clarity. When clarity fades, risk rises.

  • Russia may judge that NATO’s resolve is fractured and test its boundaries further.
  • China may interpret the moment as evidence that the global response to aggression will be slower and more divided, increasing risk around Taiwan.
  • European states such as Poland are already signalling that they may need to pursue nuclear options for their own security.

These are not abstract concerns. They are the predictable consequences of a world where norms weaken and alliances strain.

Hungary: The Most Likely Fault Line

The next major test for NATO may not be a conventional military attack. It may be political capture inside a member state. Hungary is the most vulnerable point in the alliance’s architecture.

With Viktor Orbán slipping in the polls, Russia has every incentive to pursue a political, not military, strategy: support him as a compliant partner, an autocratic dictator for life – similar to Belarus – while keeping Hungary inside NATO and the EU. This would create constitutional paralysis for both organisations, neither of which has a mechanism to expel a hostile member.

The dilemma is not whether NATO would defend a government aligned with Russia. The real test is whether it would defend a population resisting a leader who is dragging the country toward an adversary. A de facto civil conflict creates a grey zone where intervention becomes politically fraught and ethically complex — precisely the environment adversaries seek to exploit.

The Impact on Allies Who Share Our Principles

Canada, Australia, New Zealand, and many European nations remain aligned with the UK’s core values: rule of law, democratic accountability, and the rejection of aggression. But the UK’s ability to stand with them is weakened when:

  • defence capability is insufficient
  • resilience is fragile
  • strategic autonomy is limited
  • dependency on the US shapes decisions more than UK principles

Resilience is not just about survival. It is about being a credible partner.

Resilience as the Foundation of Ethical Autonomy

Everything converges on a single point: resilience is what allows a nation to act ethically when the world becomes morally ambiguous. Without resilience, a nation cannot choose its own path. It can only choose between the preferences of stronger powers.

Rebuilding that foundation requires:

  • Defence capability that is credible and sustainable.
  • Food security that ensures the population can be supported under stress.
  • Energy independence that reduces vulnerability to external shocks.
  • Technology sovereignty that protects critical systems.
  • Manufacturing depth that enables rapid adaptation.
  • Civil protection that strengthens societal resilience.

A Practical Starting Point: Food Resilience

Food is the foundation of every other form of resilience. A nation that cannot feed itself cannot sustain itself during crisis, cannot support its allies, and cannot act independently. But food resilience is not only a wartime concern. Any disruption to the global supply chain — whether geopolitical, environmental, or biological — can create immediate pressure.

The COVID‑19 pandemic exposed this fragility. Supplies ran low. Online delivery slots were booked weeks in advance. Vulnerable people were forced into supermarkets because they had no alternative. My own family had a buffer because I had been monitoring events in China months earlier and had gradually built supplies. Most people had no such warning. Supermarkets improvised their own rationing systems, limiting items per shopper without regard for household size, whether someone was shopping for a vulnerable neighbour, or whether they were supporting multiple families.

A practical first step is to convene a cross‑government working group – involving the Department of Health, DEFRA, the FSA, the Home Office, Defence, and the British Retail Consortium – to define what nutritionally sufficient rationing would look like in the modern age. From there, the UK can build the agricultural capacity, supply‑chain systems, and retailer integration needed to activate such a framework at short notice.

This is not about wartime planning. It is about sovereign capability – ensuring the UK can support its population under any form of disruption, and enabling communities to support one another without fear of scarcity.

Conclusion

The UK stands at a strategic crossroads. The world is becoming more unstable, alliances more strained, and norms more fragile. In such an environment, ethical foreign policy is only possible when a nation has the capability to act independently.

Rebuilding that capability – through defence, resilience, and sovereign systems – is not optional. It is the foundation of ethical autonomy. And it begins with the basics: ensuring the UK can feed itself, protect itself, and stand with allies because it chooses to, not because it has no alternative.
