That order has now reached a decisive historical inflection point. The foreign policy paradigm forged during the two administrations of United States President Donald Trump — marked by unilateralism, transactional nationalism, and a recalibration of historic alliances — represents a sharp break from prior international norms. Combining coercive leverage with strategic media manipulation, this shift has heralded a new foreign policy phenomenon: Trumpism.
By combining assertions of national sovereignty with an anti-establishment tone, Trumpism systematically challenges the core assumptions that had underpinned global governance for generations.
At its core, it represents a deliberate move away from grand, Western-dominated global leadership towards a decentralised, issue-specific, and deeply transactional international order.
Trumpism’s operational strategy has replaced traditional multilateral commitments with a hardheaded focus on economic statecraft and national interest. Foreign policy engagements have been explicitly tethered to domestic economic priorities: reindustrialisation, a revitalised defence industrial base, energy dominance, balanced trade, and leadership in the financial sector.
To achieve these aims, the Trump administration has eschewed expansive multinational agreements in favour of bilateral bargains, deploying aggressive tariffs, coercive trade measures, and sanctions as primary instruments of state power.
The administration’s reliance on expansive sanctions regimes and aggressive extraterritorial enforcement has ignited fierce global debates regarding international law, state sovereignty, and the legitimate limits of national jurisdiction.
Under the banner of “peace through strength”, Trumpism has integrated legal, economic, and security mechanisms to pressure allies and adversaries alike. Law enforcement operations and national security objectives have been routinely repurposed as direct tools of foreign policy.
This transactional posture has extended directly into collective defence and security architectures, most notably NATO. Trumpism has brought intense scrutiny to Western defence burden-sharing arrangements, highlighting severe imbalances where the US had borne a disproportionate share of costs and strategic risks.
The systemic consequences of Trumpism have reverberated across every layer of the global governance hierarchy.
In multilateral forums, the administration has displayed unprecedented ambivalence and unpredictability, frequently reneging on established international agreements and disengaging from multilateral institutions.
This volatile leadership style has exposed deep vulnerabilities within global governance, accelerating the fragmentation of the post-Cold War liberal international order.
A prominent casualty of this institutional disruption has been the United Nations, particularly the UN Security Council. Trump’s policies have magnified existing debates over the UNSC’s legitimacy, representation, and effectiveness.
Observers have noted that entrenched geopolitical rivalries, institutional inertia, and structural hierarchies rooted in the colonial era had already left the UNSC paralysed—trapped in a pre-contemplation stage of reform rather than delivering substantive structural changes. US institutional disengagement has further compounded this inertia, raising fundamental questions about the long-term durability and authority of international security bodies.
While proponents have argued that the Trump administration is seeking to drive necessary institutional reform through selective, high-level engagement—such as collaborating with like-minded allies and engaging the UN secretary-general on shared priorities—critics have viewed these moves as prioritising immediate national interests over global stability.
As the US is stepping back from global stewardship, the resulting power vacuum is catalysing a profound restructuring of international politics. Middle powers and regional blocs are increasingly stepping forward to bridge governance gaps.
These actors have begun constructing regional frameworks and issue-specific coalitions, casting them as vital supplements — or direct alternatives — to traditional Western-dominated institutions.
This global pivot has ignited a fierce debate among international relations scholars and policymakers regarding Trump’s legacy.
On the one hand, some argue that the disruptions he has caused are a catalyst for reform and systemic resilience. By forcing middle powers and non-Western nations to take greater ownership of regional security and economic coordination, Trumpism is fostering a more plural, inclusive, and realistic global order capable of addressing modern geopolitical realities.
Others are warning that US disengagement from multilateral commitments has…
