That operation, ordered in the final year of Donald Trump's presidency, now stands as the starkest symbol of a deliberate and sweeping project, the dismantling of the international order constructed in the wake of the Second World War. His administration did not merely challenge this system, it actively worked to bury its foundational principles, treating the institutions and norms of the late 20th century as artifacts to be discarded.
The pillars of that order were familiar and long-standing, multilateral alliances like NATO, trade agreements woven into complex global supply chains, and arms control treaties designed to manage existential threats. The Trump doctrine approached each as a constraint on national sovereignty or an unfair burden. The withdrawal from the Paris Climate Accord and the Iran nuclear deal were not isolated disputes but part of a coherent pattern of repudiation.
This was not chaos, but a conscious ideology of disintegration. The president's "America First" mantra was an explicit rejection of the collective security and liberal democratic project that defined the West's post-Cold War stance. Relationships once described as alliances became transactional negotiations, where the very value of the partnership was subject to public doubt and financial reckoning.
A Legacy Defined by Dismantling
Consequently, Trump's legacy in foreign affairs is defined less by what he built than by what he tore down. The architecture painstakingly assembled by generations of diplomats from both American political parties lies in deliberate disrepair. The strike against Soleimani exemplified this, upending decades of established red lines and protocols for engaging Iran through a sudden, unilateral act of force.
The implications extend far beyond any single action or region. The credibility of treaties and America's word as a negotiating partner has been fundamentally altered. Allies now operate with the understanding that American commitments can be reversed by a single tweet, while adversaries are forced to calculate based on unpredictable, personalist diplomacy rather than established statecraft.
As a new administration surveys the global landscape, it inherits a terrain deliberately cleared of the old order. The question is no longer about reforming the 20th century's systems, but about what, if anything, can be built in the vacant space left behind. The era that began in 1945 was declared over not with a peace treaty, but with a sustained campaign of abandonment.
