The Multilateral Mirage: What Happens When the World Order Unravels?

The United Nations, once a beacon of international cooperation and collective security, is now struggling to stay relevant in an increasingly fragmented world. Donald Trump’s visit to UN headquarters in New York in September 2025 was marred by a broken escalator, blamed on his own camera operator. The incident served as a stark reminder that the global order is facing a crisis of its own.

The post-World War II era has given way to an era of great power competition, with nations vying for influence in a rapidly shifting landscape. The US, under Trump’s leadership, withdrew from numerous international organizations and treaties, leaving behind a vacuum that other powers were eager to fill. China is positioning itself as a key player in this new world order, while the BRICS alliance continues to grow in importance.

The implications of this shift are far-reaching and complex. For one, the era of American dominance may finally be coming to an end – but what does that mean for the global economy, international relations, and human security? Mark Leonard of the European Council on Foreign Relations observed: “It is time to acknowledge that the old order really has disappeared and to plot a new approach to geopolitics.”

The Decline of Multilateralism: Causes and Consequences

The collapse of multilateralism reflects deeper structural flaws in the global order. Teresa Nogueira Pinto, an expert on globalization and Africa at Lusofona University, notes that “the framework of multilateralism, which is connected with the world after World War II… I would say that it’s all over.” She cites the failures of peacekeeping and peacebuilding missions as a stark reminder of the need for fundamental reform.

Not everyone agrees on the extent to which multilateralism has declined. Johannes Thimm of the German Institute for International and Security Affairs offers a more nuanced view: “I do not agree that this era is already completely over.” He highlights the continued importance of international law and diplomatic conventions in governing state relations – but acknowledges the growing trend of international law violations.

The Rise of Multipolarity

As the US withdraws from its traditional role as global leader, other powers are scrambling to fill the gap. China’s rise is perhaps the most significant development, with Beijing seeking to establish a new world order that reflects its own interests and values. Meanwhile, the BRICS alliance continues to expand its membership and influence, posing a challenge to Western dominance in international affairs.

African nations, caught between competing great powers, are repositioning themselves in response to the shifting global landscape – but at what cost? Pinto noted: “It’s very, very hard to even imagine a reform” of institutions like the UN Security Council.

The Future of International Relations

As we look ahead to the next five years, it is clear that the world will be facing significant challenges and uncertainties. Nations may adapt to this new reality by forging new alliances and agreements – or the current trend of fragmentation and disorder could continue, threatening global stability and security.

The future of multilateralism will depend on our collective ability to navigate these complexities and chart a new course forward. The world order as we knew it is no more, and a new era of great power competition has begun. As nations adjust to their new roles in this multipolar world, effective communication, diplomacy, and cooperation will become essential for navigating the intensifying rivalries and shifting allegiances.

In reexamining our assumptions about global governance, international relations, and the role of nations in shaping the world order, we must prioritize negotiation and compromise. The art of finding common ground will be crucial as nations navigate this uncertain future.
