How to follow the middle power playbook

“The UK is going through a period of adjustment. Both the world and its place in it are rapidly changing, leaving the country wondering whether it’s still globally relevant. Roli Asthana argues that the best route out of this situation is for the UK to follow the middle power playbook and learn from the states that thrive by their position in the middle.

The UK is not accustomed to thinking of itself as “in the middle.” For decades, its strategic identity rested on two pillars: a leading architect of the post‑war liberal order and a pivotal transatlantic power with privileged access to Washington, Brussels and global markets. Yet the world that sustained those roles is dissolving. Trade routes are disrupted by conflict, climate shocks are hitting supply chains, technology has become a battleground for strategic advantage and great‑power competition now shapes everything from semiconductor access to shipping insurance. In this fractured landscape, the UK increasingly faces the dilemmas that define today’s middle powers. This is not a comment on Britain’s capabilities but a reflection of a structural reality in which power is dispersed, coalitions are fluid and economic interdependence is increasingly weaponised. Middle powers such as South Korea, Australia, Türkiye, Indonesia, the UAE and Brazil have been navigating this environment for years. They are neither passive rule‑takers nor dominant system‑shapers. Instead, they operate in the grey zones of a contested order, where agility matters more than hierarchy and where influence comes from leverage rather than legacy. If post‑Brexit Britain wants to remain globally relevant, it must learn from how these states survive and thrive in the middle, and it must do so while managing its most complicated relationship: the one with the United States. The middle power playbook Middle powers have long understood that the world is no longer organised around neat blocs or predictable alliances. They face a system defined by selective alignment, geoeconomic pressure and constant exposure to external shocks. Their behaviour reflects this reality. They build flexible, purpose‑driven partnerships that shift depending on the problem at hand, as seen in South Korea’s ability to work with the United States on security, China on trade and ASEAN on regional diplomacy. They treat geoeconomic tools as central to national strategy, whether through Australia’s supply‑chain rewiring after Chinese sanctions , Indonesia’s use of nickel reserves to attract electric‑vehicle investment or Singapore’s deployment of regulatory excellence as a source of national power. Above all, they maintain a clear‑eyed assessment of where their leverage lies, focusing on the chokepoints, capabilities and convening power that give them bargaining strength rather than pretending to lead in every domain. Why the UK faces middle‑power dilemmas Post‑Brexit Britain is not a middle power in the traditional sense. It retains a global financial centre, a nuclear deterrent, a permanent UN Security Council seat, world‑class universities and deep diplomatic networks. Yet the structural environment has changed faster than the UK’s strategic posture. The dilemmas now confronting the UK mirror those faced by middle powers everywhere. If post‑Brexit Britain wants to remain globally relevant, it must learn from how these states survive and thrive in the middle, while managing its most complicated relationship: the one with the United States. Britain must balance economic interdependence with strategic autonomy in supply chains, energy and technology. It must navigate sanctions, export controls and geoeconomic coercion without becoming collateral damage in US–China rivalry. It must remain influential in a world of fluid coalitions in which mini-lateral groupings increasingly shape outcomes. And it must compete in new arenas of power such as critical minerals, digital infrastructure, AI governance and climate adaptation. The UK is no longer operating in a world where historical status guarantees strategic relevance. It must earn influence through agility, leverage and strategic clarity, the very behaviours that define successful middle powers. What the UK can actually do: lessons from middle powers What does this mean in practice? The UK can begin by building issue‑based coalitions in areas where it has real leverage. Britain has the capacity to play a central role in maritime security in the Indo‑Pacific, drawing on naval expertise and the momentum generated by the Australia-UK-Australia Strategic Partnership ( AUKUS ). It can lead in climate‑resilient finance by using the City of London’s green‑finance ecosystem to shape global norms. It can continue to position itself as a global convener on AI safety and standards. And it can use its regulatory strengths to drive transparency and governance in critical‑minerals supply chains. These coalitions should be flexible, mini-lateral and problem‑driven, mirroring the approach that has allowed middle powers to remain influential despite structural constraints. The UK can begin by building issue‑based coalitions in areas where it has real leverage. The UK also needs a coherent geoeconomic strategy. Middle powers treat geoeconomics as national strategy rather than a niche discipline, and Britain should do the same. This requires integrating trade, industrial policy, investment screening and technology regulation into a single strategic framework. It means identifying supply‑chain vulnerabilities in semiconductors, pharmaceuticals and critical minerals. It involves using the UK’s regulatory power to shape global standards in fintech, AI and green finance. And it calls for aligning development finance with strategic objectives, following the example of Australia and Japan in the Pacific. None of this is protectionism; it is strategic positioning. Britain must also focus on areas of true comparative advantage. Middle powers succeed by concentrating on the few domains where they can shape outcomes. For the UK, these include financial services, legal and regulatory expertise, biotech and life sciences, offshore wind and green innovation, advanced research and university networks, and defence and cyber capabilities. A realistic strategy is more powerful than an expansive one. Strategic ambiguity will also be essential. Middle powers excel at maintaining relationships across rival blocs without appearing unreliable. The UK will need similar dexterity, especially in managing ties with the United States, the European Union and Indo‑Pacific partners while maintaining a workable relationship with China. This is not fence‑sitting; it is strategic optionality. Resilience must become a source of competitive advantage. Middle powers understand that resilience in supply chains, infrastructure and regulation is not merely defensive. It attracts investment, strengthens bargaining power and enhances national credibility. For the UK, this means accelerating grid and port upgrades, securing long‑term energy contracts, diversifying sources of critical minerals and strengthening cyber and data‑infrastructure resilience. Resilience is strategy. Managing the tricky relationship with the US Managing the relationship with the United States will be central to Britain’s ability to operate effectively in the middle. The UK’s relationship with Washington is its greatest asset and its greatest constraint. Middle powers offer three lessons for managing asymmetric partnerships. First, they align where interests converge rather than where history dictates. Australia supports the United States on security but diverges on China trade, and South Korea cooperates on semiconductors while hedging on supply chains. The UK should adopt a similarly selective approach, supporting the United States on defence and intelligence while carving out autonomy on trade, technology and climate. Second, they offer value rather than deference. The UK’s relationship with Washington is its greatest asset and its greatest constraint. The United States respects capability and problem‑solving, not nostalgia. Britain should position itself as the partner that can deliver on maritime security, AI governance and financial regulation, areas where Washington needs allies. Third, they maintain strategic space by cultivating multiple anchors. For the UK, deeper cooperation with the European Union on standards and with Japan and Australia on supply chains will reduce vulnerability to shifts in US policy. Managing the US relationship is not about distancing or doubling down; it is about strategic balance. Operating in the middle Is not a downgrade The phrase “middle power” can sound like a demotion, yet in today’s world the middle is where the action is. Middle powers are the swing states of the global economy. They are the brokers, the innovators and the coalition‑builders. They shape outcomes not through dominance but through agility. For the UK, the challenge is not to reclaim a lost great‑power status but to adopt the strategic behaviours that allow middle powers to thrive in a fragmented order. This means building flexible coalitions, mastering geoeconomic tools, investing in areas of true leverage, balancing the US relationship with strategic autonomy and approaching the world with clear‑eyed realism rather than nostalgia. In a system where the rules are being rewritten, influence belongs to those who can navigate complexity with confidence. Britain’s future will depend not on where it once stood but on how effectively it learns to operate in the middle. Enjoyed this post?
