In 2025, a new political order is emerging—not through treaties or grand diplomatic accords, but through rejection. A wave of populist leaders—Javier Milei in Argentina, Narendra Modi in India, and Giorgia Meloni in Italy—is actively dismantling the post-World War II framework of multilateralism that once defined global cooperation. Their rhetoric, actions, and policies reveal a coordinated break from globalist norms in favor of nationalism, sovereignty, and protectionism.
This anti-globalist surge is not occurring in a vacuum. It is the direct result of a series of political upsets—elections driven by populist discontent—and the breakdown of trust in global trade governance, as seen in the rise of trade wars and economic decoupling. But if multilateralism is being cast aside, what replaces it? And are we entering a world where shared problems go unsolved due to fractured cooperation?
The Populist Triad: Milei, Modi, and Meloni
Javier Milei: Sovereignty Above Solidarity
In Argentina, President Javier Milei has built his foreign policy on the idea that multilateralism is a threat to national autonomy. His administration has rejected gender-inclusive language and climate initiatives at the Organization of American States (OAS) and refused to endorse the World Health Organization’s pandemic preparedness treaty. Milei’s Foreign Minister, Diana Mondino, has bluntly declared that Argentina will not “allow an international body to infringe upon our sovereignty.”
This stance is more than symbolism—it’s policy. Argentina under Milei is purposefully disentangling from cooperative health governance and climate action, reflecting a broader worldview where international institutions are perceived as obstacles rather than facilitators.
Narendra Modi: Strategic Nationalism in a Global Arena
India’s Narendra Modi takes a more nuanced but equally nationalist approach. His “Atmanirbhar Bharat” campaign—meaning “self-reliant India”—reflects a strategic pivot away from economic interdependence. While India still participates in multilateral forums like the G20 and BRICS, it increasingly does so on its own terms, resisting external pressure on trade, human rights, and regional diplomacy.
India’s refusal to align fully with Western blocs or China-centric initiatives shows a calculated form of selective engagement. Modi’s India champions strategic autonomy over collective decision-making, engaging globally when it suits national interests but resisting any binding commitments.
Giorgia Meloni: Conservatism as Foreign Policy
In Europe, Giorgia Meloni champions a form of conservative nationalism that sees globalism as a leftist, elitist threat to tradition. At CPAC 2025, she stood shoulder to shoulder with Milei, Modi, and Donald Trump, declaring war on “woke ideology,” open borders, and multilateral constraints.
Meloni’s rhetoric is clear: multilateralism is a tool of liberal elites to impose values and regulations that conflict with national identity and conservative culture. Her Italy supports closed borders, energy nationalism, and “family-first” policies over international human rights frameworks or environmental goals.
Election Upheavals: Populist Winds from the Ballot Box
What these leaders share is not just ideology but the political momentum of electoral upset. Milei’s dramatic rise in Argentina was fueled by economic chaos and disillusionment with establishment parties. Modi has turned a decade-long incumbency into a populist juggernaut, thriving on Hindu nationalist rhetoric and anti-globalist posturing. Meloni, meanwhile, converted a fringe party into a ruling coalition by channeling discontent over migration, European bureaucracy, and inflation.
These election outcomes reflect a deeper global mood: a rejection of the neoliberal consensus, rising nationalism, and the public’s hunger for leaders who promise to put “their country first.” Multilateralism, to these voters, is synonymous with bureaucracy, lost sovereignty, and elite betrayal.
Trade Wars and the Economic Disintegration of Cooperation
While the political arena is experiencing nationalist revival, the economic sphere is equally turbulent. Global trade has become a battlefield rather than a bridge. The World Trade Organization (WTO), long the pillar of international commerce, is increasingly powerless—its dispute resolution system effectively paralyzed and its relevance challenged by nationalist trade strategies.
Milei’s Argentina is raising trade barriers under the guise of economic nationalism. Modi’s India continues to restrict foreign companies and is building supply chains independent of Chinese influence. Meloni supports “Made in Italy” policies aimed at boosting domestic industry at the expense of EU-wide competition rules.
Meanwhile, major economies like the U.S. and China are locked in tariff wars, technology bans, and supply chain decoupling, signaling a shift from global integration to economic fragmentation. In this environment, multilateral institutions are not just ignored—they’re actively undermined.
What Comes After Multilateralism?
If multilateralism is being hollowed out by populist nationalism, what’s filling the void? Several trends offer insight into the emerging global governance patchwork:
- Bilateralism and Regionalism: Countries are prioritizing bilateral agreements (e.g., U.S.–India) and regional frameworks (e.g., RCEP, USMCA) that offer greater control and less bureaucracy than global treaties.
- Minilateralism: Rather than comprehensive multilateral accords, states are forming small, flexible coalitions on specific issues—like digital policy, semiconductors, or security alliances.
- Sovereignty-First Governance: Populist regimes prioritize policies that reassert border control, economic protection, and regulatory autonomy, often at the cost of collaborative problem-solving.
- Private and Tech Sector Governance: With states retreating from global leadership, corporations and tech firms are increasingly setting de facto international standards—from AI ethics to digital trade protocols.
Yet these emerging frameworks are fragmented, inconsistent, and often lack enforcement mechanisms. The global commons—climate, health, security—requires cooperation that these models cannot always provide.
The Risks of a Fragmented Future
The collapse of multilateralism is not just a diplomatic issue; it’s a threat to global stability. Transnational problems—climate change, pandemics, cyber threats—do not respect national borders. When states refuse to cooperate, the consequences are shared by all.
Moreover, the ideological alignment among populist leaders across regions hints at an alternative global order, one built not on shared rules but on mutual admiration of nationalism, conservatism, and unilateralism. The Milei-Modi-Meloni-Trump axis represents a form of global counter-globalism, one that may deepen polarization and destabilize efforts to build consensus.
A Turning Point in Global Governance
The rejection of multilateralism by populist leaders like Milei, Modi, and Meloni marks a decisive shift in international relations. Election upsets and trade wars have fueled nationalist fervor, undermining the institutions that once ensured global stability.
What replaces multilateralism remains uncertain, but the path ahead is likely to be fragmented, unpredictable, and marked by ideological conflict. To avoid a future where global challenges go unaddressed, the international community must find new models of cooperation—or risk irrelevance in an age of sovereign populism.
