Jeffrey Sachs has been warning for years that the “unipolar moment” was never real — and in this conversation with Glenn Diesen, he lays out the clearest case yet. Trump’s failure in the Iran War, Sachs argues, didn’t just expose the limits of one administration. It exposed the limits of the entire post‑Cold War American project: a foreign policy built on illusions of dominance, ideological entitlement, and a refusal to accept a multipolar world already taking shape.

Sachs traces the long arc of Western hegemony — from the European empires to Washington’s brief moment of post‑1991 triumphalism — and shows how the Iran conflict has become the breaking point. The U.S. could not impose its will on Tehran. It could not bend Russia through sanctions. It cannot contain China’s rise. And yet its political class continues to behave as if history stopped in 1991.

This interview is not just analysis. It’s an autopsy of an empire that still believes it is immortal.

Jeffrey Sachs: Trump’s Defeat in Iran and the Unmistakable Decline of U.S. Empire

In a sweeping, historically grounded conversation with Glenn Diesen, Jeffrey Sachs argues that the Iran War has become the moment when the mythology of American omnipotence finally collided with reality. The United States, Sachs says, has reached the limits of its power — not because of one failed military campaign, but because the world that once made U.S. dominance possible no longer exists.

The End of Western Hegemony Didn’t Start With Trump — It Started in 1945

Sachs begins by placing the Iran conflict inside a much longer arc. Western dominance — first European, then American — was never permanent. It was a historical anomaly built on industrialization, colonial extraction, and technological monopolies that could not last. After World War II, as Europe’s empires collapsed, Asia began a slow but unstoppable rise: literacy, industrialization, urbanization, and technological catch‑up.

By the time the Soviet Union dissolved in 1991, the U.S. mistook a temporary vacuum for permanent supremacy. Washington declared itself the “indispensable nation,” embraced the fantasy of a unipolar world, and built a foreign policy on the assumption that no rival could ever emerge.

Sachs’ point is blunt: the unipolar moment was an illusion from the start.

Iran as the Breaking Point

The Iran War, Sachs argues, revealed what Washington has refused to admit: the U.S. can no longer impose outcomes on major regional powers. Iran survived sanctions, proxy warfare, covert operations, and direct confrontation. It maintained internal cohesion, strengthened regional alliances, and exposed the limits of U.S. coercive power.

For Sachs, this is not just a military failure — it is a strategic and ideological one. The U.S. political class still behaves as if any country that resists American pressure is violating the natural order. Iran’s refusal to submit is treated not as geopolitics but as heresy.

The Collapse of the “Choke Point” Myth

One of the most striking themes in the interview is Sachs’ dismantling of the belief that the U.S. can control global systems indefinitely. Whether it’s SWIFT sanctions, financial blockades, or military threats, Washington has repeatedly overestimated its leverage. Russia survived the “nuclear option” of financial isolation. China built parallel systems. Iran adapted.

The idea that the U.S. can freeze economies at will, Sachs says, belongs to a world that no longer exists.

The Rise of Asia: The Real Story Washington Ignored

Sachs emphasizes that while Washington obsessed over military dominance, the real shift was happening elsewhere. Asia — home to 60% of humanity — was reindustrializing, innovating, and surpassing the West in key technologies. China is now a peer competitor in manufacturing, infrastructure, and advanced industries. India is rising. Southeast Asia is integrating.

The Iran War, in Sachs’ telling, is not an isolated failure. It is the moment when the U.S. ran headfirst into a world it no longer controls.

Ideology as a Substitute for Strategy

Sachs and Diesen discuss how Western elites continue to rely on 19th‑century narratives of civilizational superiority — the “garden vs. jungle” worldview — to justify policies that no longer work. This ideological hangover blinds policymakers to the structural changes reshaping global power.

The result is a foreign policy that oscillates between denial and escalation, unable to accept that other nations have agency, interests, and the capacity to resist.

The American Security Establishment Cannot Imagine a Multipolar World

Sachs argues that the U.S. foreign policy establishment — from think tanks to Congress — is trapped in a mindset that sees any independent power as a threat. Russia cannot be allowed to remain a great power. China cannot be allowed to rise. Iran cannot be allowed to resist. Even India, Sachs notes, will eventually be treated with suspicion.

This worldview makes diplomacy nearly impossible. It also guarantees perpetual conflict.

Trump’s Defeat Was Structural, Not Personal

While the interview discusses Trump’s role, Sachs frames the Iran failure as a symptom of deeper forces. No U.S. president — Republican or Democrat — can reverse the long‑term decline of Western dominance or the rise of Asia. The problem is not Trump’s personality but Washington’s refusal to adapt to a world where it is no longer the sole superpower.

A Final Warning: Empires Fall When They Cannot Adjust

Sachs ends with a historical reminder: technological advantages fade, economic gaps close, and empires that cling to outdated assumptions collapse under their own weight. The Iran War, he suggests, is the moment when the U.S. was forced to confront this reality — and chose denial instead.

The question now is whether Washington can accept a multipolar world, or whether it will continue to fight unwinnable battles in pursuit of a past that cannot be restored.
