Trumpism and the Reshaping of the World Order

The world order built after World War II—rooted in multilateral institutions and Western-led governance frameworks—stands at a historic inflection point. The foreign policy of US President Donald Trump across his two terms, marked by unilateralism, transactional nationalism, and alliance rebalancing, is widely seen as a clear break from previous international norms. The combination of coercive pressure and media strategy has given rise to a new phenomenon: Trumpism.

At the core of Trumpism lies an assertion of national sovereignty and an anti-elite tone, challenging the foundational assumptions of global governance. Instead of a broad Western global leadership role, this administration aims for a decentralized, issue-specific, and heavily transactional international order.

The Pillars of Transactional Policy

The Trump administration's operational strategy has replaced traditional multilateral commitments with a hard focus on economics and national interest. Foreign engagements are tightly linked to domestic economic priorities such as reindustrialization, rebuilding the defense industrial base, energy independence, trade balance, and financial leadership.

Instead of multilateral agreements, the administration favors bilateral deals, using tariffs, trade coercion, and sanctions as primary tools. The expanded use of sanctions regimes and controversial extraterritorial enforcement has sparked intense debates over international law and the limits of sovereignty.

Under the banner of “peace through strength,” Trumpism integrates legal, economic, and security mechanisms to pressure both allies and adversaries. Law enforcement actions and national security objectives are wielded as direct instruments of foreign policy. NATO serves as a prime example, with the administration sharply criticizing the imbalance in burden-sharing, where the US bears a disproportionate share of the costs and strategic risks.

Breaking Institutions and Systemic Paralysis

The consequences of Trumpism ripple across all layers of global governance. In multilateral forums, the US administration has shown inconsistency and unpredictability, frequently withdrawing from signed international agreements and ceasing participation in multilateral bodies. This has accelerated the fragmentation of the post-Cold War liberal order.

The United Nations, particularly the Security Council, is among the most visible victims. Trump's policies have deepened debates over the legitimacy, representation, and effectiveness of the Council. Observers argue that geopolitical rivalry, institutional inertia, and a hierarchical structure dating back to the colonial era have left the Security Council paralyzed. The lack of active US engagement has further exacerbated this condition.

While supporters argue that the Trump administration is pushing institutional reform through selective cooperation with allies, critics view these moves as prioritizing short-term national interests over global stability.

A Multipolar and Regionalized Order

As the US retreats from global governance, the power vacuum is driving a restructuring of international politics. Middle powers and regional blocs are stepping forward to fill the gap with issue-based frameworks and coalitions, seen as either complements to or replacements for traditional Western-led institutions.

Scholars and policymakers are fiercely debating Trump's legacy. One side argues these disruptions serve as a catalyst for reform, forcing non-Western nations to take greater responsibility for regional security and economics. The other warns that US withdrawal from multilateral commitments has broken collective security arrangements and eroded institutional legitimacy, creating prolonged strategic competition and dangerous governance gaps.

Redefining Power

Trump's foreign policy cannot be dismissed as a temporary aberration or mere stylistic change. It deserves the label Trumpism because it has forged a distinct, replicable diplomatic model. By deliberately employing unpredictable diplomacy, prioritizing national prosperity over institutional continuity, and asserting absolute sovereignty, Trumpism is redefining how a great power wields influence in the modern era.

Trump's foreign policy will leave an indelible mark on the international system. By challenging the foundations of the liberal order, it will permanently alter the balance of power, pushing the world into a new era marked by decentralized power, rising regionalism, and a continuous search for new governance models.
