As the U.S.-led international order recedes, global stability fragments into a “rotten-tail world.” According to foreign policy analysis by Mark Leonard published in Foreign Affairs, America’s financial backers have lost interest in underwriting its further development, leaving states to improvise survival strategies amid diplomatic decay, economic contagion, and strategic chokepoints.
In Plain English: The Clinical Takeaway
- Systemic Decay: The rules-based international order is breaking down because its main financial backers, the American people, have lost interest in underwriting its further development, leaving no alternative provider stepping in to take over.
- Strategic Improvisation: Much like urban inhabitants occupying unfinished construction projects—known in China as lanwei lou or “rotten-tail buildings”—nations must repurpose obsolete diplomatic and economic frameworks to survive an unstable environment.
The Metaphor of the Rotten-Tail World
Five years ago, the Chinese housing market crashed, leaving thousands of unfinished apartment buildings across the country. Citizens who had bet all their savings on indefinite expansion found themselves improvising shelter within concrete skeletons, utilizing bed sheets as walls and cooking on makeshift stoves. This phenomenon—termed lanwei lou—serves as a stark metaphor for the current trajectory of the U.S.-led rules-based international order, as detailed in recent foreign policy assessments.
For decades, this architecture of global governance expanded. However, it was never fully accepted by major rivals like China and Russia, and it was resented by assertive middle powers. Today, its main financial backers—the American people—have lost interest in underwriting its further development. With no alternative provider stepping in to take over, a fragmented, disorderly geopolitical landscape is taking shape.
Cognitive Dissonance Among U.S. Allies
Traditional allies of Washington remain trapped in outdated strategic paradigms, failing to recognize that Washington has withdrawn its support from the old order and from them. During the July 2026 NATO summit, European leaders engaged in what can only be described as surreal diplomatic theater. Fearing sudden abandonment by Washington, European leaders pledged tributes to U.S. President Donald Trump in the form of arbitrary defense spending increases—unrelated to their own defense analysts’ assessments—in the hope that he would not withdraw from the alliance.
Parallel vulnerabilities persist across the globe. In the Pacific, Australia is plowing ahead with investments in AUKUS, its trilateral security partnership with the United Kingdom and the United States, subsidizing the U.S. industrial base even as American commitments falter.
The Illusion of Ideological Solidarity
A central pillar of post-Cold War Western strategy has been the belief that shared democratic values would bind allies together against authoritarian adversaries such as China, Iran, Russia, and North Korea. Yet, historical precedent demonstrates the fragility of this assumption. Following the 2014 invasion of Ukraine, U.S. allies continued trading with Russia. Similar economic pragmatism has triumphed regarding China, despite its repression of Uyghurs and its crackdown in Hong Kong in recent years.
Furthermore, current U.S. political leadership under Donald Trump has signaled a transactional approach to foreign policy, assuring a gathering of investors and Saudi leaders in May that Washington won’t be “giving you lectures on how to live or how to govern your own affairs.” As Washington sheds its ideological posture, allied capitals can no longer rely on democratic solidarity as an automatic insurance policy against global instability.
| Metric | The U.S.-Led Order (Legacy) | The Post-American “Rotten-Tail” World |
|---|---|---|
| Primary Underwriter | United States (American people) | None (No alternative provider) |
| Core Mechanisms | Rules-based institutions (WTO, UN, NATO) | Flexible and artisanal responses, regional hedging, tactical improvisation |
| Allied Strategy | Reliance on extended deterrence and ideological alignment | Cognitive dissonance, arbitrary defense spending, isolated adaptation |
| Risk Profile | Institutional gridlock; predictable enforcement | Fragmentation, contagion, weaponized chokepoints |

Navigating the Fragmentation
The contemporary global landscape does not constitute a short interregnum between a U.S.-led order and a Chinese-led one. Instead, the international community faces a period without any order at all—swept by fragmentation, contagion, and strangulation or the temptation to weaponize a wide variety of geographic, economic, and technological chokepoints. States and institutional leaders failing to acknowledge this reality risk severe strategic vulnerability. Developing flexible and artisanal responses to regional crises will replace grand strategy as the primary requisite for state survival in an unmoored world.
