Geopolitics in 2026: The Forces Reshaping the World Order
The international order that governed global affairs since 1945 — built on US primacy, multilateral institutions, and an open trading system centred on the dollar — is fracturing. This is not a temporary disruption caused by any single leader, conflict, or crisis. It is a structural shift driven by the rise of China, Russia’s strategic reorientation eastward, the emergence of BRICS as an economic bloc, the weaponisation of the dollar through sanctions, and the growing refusal of the Global South to accept a world order designed without its input. Understanding these forces is not optional for anyone who wants to make sense of the headlines — it is the foundation of informed citizenship in the 21st century.
- → The unipolar moment — the period of unchallenged US dominance after 1991 — is over. A multipolar world is emerging, but its rules, institutions, and hierarchies are still being contested
- → The Ukraine war is not primarily about Ukraine: it is a proxy conflict over the fundamental question of whether NATO can expand indefinitely eastward — a question Western and Russian strategists answer completely differently
- → China’s rise is the defining geopolitical fact of the 21st century — and the US-China competition over technology, trade, and Taiwan is the central axis of global politics
- → De-dollarisation is real but slow: the dollar’s share of global reserves has fallen from 73% (2001) to ~58% (2024), but no single alternative exists — the transition will take decades
- → Europe is caught between dependence on US security and the need for strategic autonomy — and has not yet resolved this contradiction
Fault Line 1: The End of the Unipolar Moment
From 1991 to roughly 2008, the United States operated as the world’s sole superpower — the first time in history that a single state enjoyed such a commanding position across military, economic, technological, and cultural dimensions simultaneously. This was the “unipolar moment,” a term coined by Charles Krauthammer in 1990. It produced a distinctive foreign policy logic: if America was unchallenged, it could afford to intervene anywhere, expand alliances to their natural limits, and remake the international order in its image.
That moment is over. China’s GDP (PPP) now exceeds America’s. Russia has demonstrated — whatever one thinks of its methods — that it can sustain a large-scale conventional war against the combined economic pressure of the Western alliance. The Global South increasingly refuses to align with either Washington or Moscow/Beijing, pursuing strategic autonomy instead. The institutions that underpinned US primacy — the IMF, World Bank, WTO, NATO — are contested, bypassed, or reformed. The question is no longer whether the unipolar order will persist, but what replaces it.
“The question is not whether the world is becoming multipolar — it clearly is. The question is whether the transition will be managed peacefully or through a series of conflicts that establish the new hierarchy through force.” — The central dilemma of 21st-century geopolitics.
Fault Line 2: The Ukraine War and European Security
The Russian invasion of Ukraine in February 2022 — and the US-Israeli strike on Iran in March 2026 — have fundamentally altered European security calculations. For Europe, the questions are existential: Can NATO deter Russia without the full commitment of the United States? Is European strategic autonomy — long discussed, never achieved — now a genuine necessity rather than a theoretical aspiration? And what does the Ukrainian war’s eventual outcome mean for the post-1945 principle of territorial inviolability?
The realist school of international relations — represented most forcefully by John Mearsheimer — argued from 2014 onward that NATO expansion was the primary driver of Russian behaviour, and that the West was ignoring Russia’s red lines at its peril. The liberal internationalist school argued that sovereign states have the right to choose their alliances, and that accommodating Russian demands would reward aggression. Both schools have made predictions. The test of which framework better explains actual events is now underway in real time. See our detailed analysis: Mearsheimer on Europe’s Bleak Future and Mearsheimer on the US-Israeli Attack on Iran.
Fault Line 3: The US-China Competition
The defining geopolitical contest of the 21st century is between the United States and China — not over ideology in the simple Cold War sense, but over technology, trade routes, reserve currency status, and the question of Taiwan. China’s Belt and Road Initiative has woven Chinese infrastructure investment across 150+ countries. Its military has been modernised at a pace that has alarmed Pentagon planners. Its technology sector — Huawei, CATL, BYD, DeepSeek — is competing with or surpassing American firms in strategically critical areas.
The US response has been to decouple strategically: restricting semiconductor exports, subsidising domestic manufacturing through the CHIPS Act, building Indo-Pacific security frameworks (AUKUS, the Quad), and applying tariffs. China’s response has been to accelerate self-sufficiency, deepen ties with Russia and the Global South, and push for alternatives to dollar-based financial infrastructure. This is not a trade dispute — it is a structural competition between two systems for dominance in the defining technologies and institutions of the 21st century.

Fault Line 4: BRICS and the Challenge to Western Institutions
BRICS — originally Brazil, Russia, India, China, South Africa — expanded in 2024 to include Saudi Arabia, UAE, Iran, Egypt, and Ethiopia. The bloc now represents approximately 40% of global GDP (PPP) and over 45% of the world’s population. It does not have a shared ideology, a common security framework, or a unified foreign policy. What it does have is a shared interest in reducing dependence on Western financial infrastructure — particularly the dollar payment system that allows the US to impose sanctions with global reach.
The practical implications are visible in trade: Russia and China now settle most bilateral trade in yuan and rubles. Saudi Arabia has sold oil to China in yuan. India is exploring rupee-based trade with multiple partners. None of this displaces the dollar overnight — but the direction of travel is clear.

Fault Line 5: The Global South’s Strategic Autonomy
Perhaps the most underappreciated shift in contemporary geopolitics is the assertion of strategic autonomy by countries that were previously assumed to be firmly in the Western orbit — or simply irrelevant. India refuses to sanction Russia. Brazil abstained on Ukraine UN votes. Turkey, nominally a NATO member, maintains close economic ties with Moscow and mediates between the parties. Saudi Arabia coordinates with OPEC+ against US production preferences. Indonesia, the world’s fourth most populous country, will not align with either bloc.
This is not non-alignment in the Cold War sense — a principled refusal to join either camp. It is strategic opportunism: maximising leverage by refusing to be taken for granted by any great power. The Global South has learned from decades of experience that alignment with a great power rarely delivers its promised benefits — and that refusing alignment now provides more diplomatic space than ever, given that both the US and China are actively competing for partners.

The world is not simply becoming more dangerous — it is becoming more complex in a specific way. The post-1945 order provided a framework, however imperfect, for managing great-power competition. That framework is breaking down, and the new one has not yet crystallised. In this interval — which may last decades — the risks of miscalculation, escalation, and systemic crisis are elevated. Understanding the forces at work does not make the world less dangerous, but it makes the headlines less surprising and the choices clearer. The articles in this series are written with that purpose: not to predict outcomes, but to explain the structural forces that make certain outcomes more or less likely.
