How the Weak Survive a World Without Rules

For most of the past eighty years, a small or medium-sized country had a reliable way to stay safe. It signed treaties, joined alliances, obeyed trade rules, and trusted that the strongest powers had broadly agreed to play by the same book. Finland, South Korea and Costa Rica did not need to be powerful. They needed the system to hold.

That bet is now in doubt. Washington treats allies as negotiating targets. Russia redraws borders by force. China punishes trading partners for political offences. The three largest powers increasingly look less like rivals policing each other and more like a loose cartel of the strong, each carving out a sphere where its will is law. For the roughly 190 countries that are not great powers, the question has shifted from "which side do we join?" to "how do we survive when no one enforces the rules?"

The model: balance, bandwagon, or hedge

International relations has studied this predicament for decades. The foundational framework is the choice between balancing and bandwagoning, sharpened by the political scientist Stephen Walt in The Origins of Alliances (1987). Walt's evidence — a survey of Middle Eastern and European alignments — showed that states balance not against raw power but against threat: proximity, offensive capability, and perceived hostile intent.

• Balancing means joining others against the threatening power, pooling strength to make aggression too costly. NATO is balancing at industrial scale.
• Bandwagoning means the opposite: siding with the threatening power, accepting subordination for protection or a share of the spoils. A weak state beside a hungry one may simply submit.

A third option, hedging, was catalogued later by scholars of Southeast Asia — notably Cheng-Chwee Kuik and Evelyn Goh — watching states like Singapore and Vietnam refuse to pick between the US and China. Hedging means keeping ties with all sides, becoming no one's reliable asset or reliable enemy, and preserving the freedom to switch.

In a rules-based order, small states lean on balancing through alliances. In a predatory order where the enforcers have gone rogue, the calculus shifts toward hedging — and toward an older tactic now named explicitly in defence doctrine: making yourself more trouble to swallow than you are worth.

The mechanism: how a small state makes itself indigestible

Strip away the diplomacy and the logic is coldly practical. A great power preys on the weak when the expected reward exceeds the expected cost. A survivable small state works on both sides of that equation.

Raise the cost of coercion. This is the "porcupine" strategy, argued most influentially by the US naval analyst William Murray in 2008 and since adopted as Taiwan's stated doctrine: a porcupine cannot beat a wolf, it only has to make the meal not worth the wounds. Taiwan buying cheap, mobile, hard-to-destroy missiles rather than a few prestige warships is porcupine logic. So is Finland's model of universal reserves and bunkered cities. The aim is not victory but deterrence by denial — convincing the predator that swallowing you means choking.

Lower the reward of coercion. Make yourself more useful alive and independent than conquered. A country supplying something the giant genuinely needs — rare minerals, a chokepoint port, chip-grade sand, a manufacturing niche no one else fills — buys protection with indispensability.

Multiply the predator's problems. This is hedging as insurance. Trade with China, buy security from America, keep Europe invested in your stability, and no single giant can move against you without antagonising the others. You turn vulnerability into a web of entanglements that makes you costly to touch.

Pool with your peers. One small state is prey; a dozen coordinating ones are a bloc. Middle powers that cannot balance the giants alone can balance them together — joint arms purchases, shared trade retaliation, common standards the giants must negotiate with rather than dictate to.

When you cannot change how strong the predator is, you change the arithmetic of its appetite.

The other view

The honest competing interpretation is that nothing fundamental has changed, and the "predatory order" framing is overstated.

In this reading, great powers have always bullied the weak — the rules-based order was itself written and enforced by the strongest, for their benefit, and bent whenever convenient. The current moment is noisier but not categorically new, and middle powers have always hedged. What looks like a cartel of giants may simply be ordinary great-power competition in a rough patch, and tomorrow's alignments could snap back toward rivalry — which would again let small states balance one giant against another.

What is fact: alliance commitments once treated as near-automatic are now openly transactional, and borders have been changed by force in Europe for the first time in decades. What is interpretation: whether this is a durable new order or temporary turbulence. What is unknown: whether the three great powers actually coordinate, or merely tolerate each other's spheres while quietly competing. The difference matters enormously — a genuine cartel is far harder to play off against itself than three rivals.

Where else this logic lives

The porcupine-and-hedge playbook is not really about countries. It is the survival strategy of any weak party facing a strong one who may not play fair.

A small supplier dependent on one giant customer lives this daily. The customer can squeeze margins to nothing or drop you on a whim. The supplier's defences mirror a small state's: become hard to replace (raise the cost), diversify your customer base so no single buyer owns you (multiply their problems), and build relationships with the buyer's rivals (hedge). "Never let one client be more than 20% of revenue" is the porcupine principle in a spreadsheet.

The same holds for an employee inside a firm that treats people as disposable, or the junior partner in any lopsided relationship. Safety does not come from trusting the stronger party to be fair. It comes from making your departure costly and your loyalty non-exclusive.

What to watch

The signal that distinguishes a true cartel from ordinary rivalry is coordination against third parties. If the giants begin tacitly respecting each other's spheres — America shrugging at Russian pressure on its neighbours, China and America declining to compete for the same middle powers — that points to collusion, and hedging gets harder as the exits close. If instead they keep poaching each other's partners, rivalry survives and small states retain room to manoeuvre.

The second signal is defence spending by middle powers. A genuine shift toward a predatory order shows up as porcupine buying: cheap, dispersed, denial-focused weapons, and joint procurement blocs among smaller states. That is already visible in Europe and the Pacific.

Expectation: roughly 65% that over the next five years, middle powers measurably diversify their security and trade dependencies away from any single great power — the hedging response — rather than consolidating behind one bloc. The clearest early tell will be arms deals and trade agreements that deliberately span rival spheres rather than picking a side.
