47 years of deep mistrust and misperception paved the way to war between Iran and the US — and complicate any negotiations

It has been said that trust is like glass: Once it is shattered, nothing will ever be the same. In the case of the enduring hostility between the Islamic Republic of Iran and the United States over the past 47 years, even this metaphor may be an understatement.

The tone of the relationship is indicative of this fact.

In 2020, Iran’s supreme leader denounced President Donald Trump as a “clown” who only pretends to support the Iranian people while ultimately plunging a “poisonous dagger” into their backs.

And in a U.S. version of this hostility, Trump’s special envoy Steve Witkoff said on Feb. 23, 2026, about the president’s approach to Iran: “I don’t want to use the word ‘frustrated,’ because he understands he has plenty of alternatives, but he’s curious as to why they haven’t … I don’t want to use the word ‘capitulated,’ but why they haven’t capitulated.”

The war that began on Feb. 28, 2026, hews to a familiar but dangerous pattern. Deep, historical mistrust, incompatible strategic interests, domestic political constraints on both sides, miscommunication and misperception, zero-sum thinking and repeated diplomatic overreach gradually pushed the relationship between Iran and the U.S. toward open conflict.

Rhetoric, not reality

When Tehran refused to yield to Trump’s demands, he described Iranian leaders in blunt terms: “They’re sick people. They’re mentally ill. Sick people. They are angry. They are crazy. They are sick.”

For a deeper understanding of Iran, policymakers in Washington could have looked to the insights of John W. Limbert, a distinguished diplomat with four decades of experience in Iranian affairs and a hostage during the Iran hostage crisis.

In 2008, as part of a U.S. Institute of Peace study of Iranian negotiating style, Limbert outlined 15 principles for Americans seeking successful negotiations with Iranian counterparts. Among his most important observations was that each side tends to assume the worst about the other, viewing its adversary as “infinitely devious, hostile, and duplicitous.”

Little evidence suggests that such hard-earned wisdom has informed recent rhetoric.

Instead, American leaders’ and media’s discussions of Iran over the past few decades have often relied on a familiar narrative: the portrayal of Middle Eastern leaders as irrational or “lunatic” figures ? first, revolutionary leader Ayatollah Ruhollah Khomeini, then Saddam Hussein, followed by Moammar Gadhafi, Bashar Assad, and now Ali Khamenei.

This narrative conveniently overlooks inconvenient facts.

Getting to breakdown

It was Trump who withdrew the United States from the 2015 nuclear agreement with Iran during his first term. It was also the United States that during renewed negotiations in 2025 and 2026 chose to bomb Iranian targets twice while talks were still underway.

Nor were the negotiations ever strictly bilateral. There was always an unoccupied chair at the table metaphorically reserved for a ghost participant: Israel. In my view, Prime Minister Benjamin Netanyahu skillfully used political leverage and diplomatic pressure to shape the process publicly and privately.

When it came to Iran, Trump often violated a basic principle of diplomacy: asking Iran to concede without any reciprocity. Meanwhile, Netanyahu would repeatedly move the goal posts ? asserting that Iran was on the verge of acquiring a nuclear weapon, insisting it had no right to enrich uranium on its own soil, demanding the dismantling of its nuclear infrastructure, calling for the elimination of its ballistic missile capability, and ultimately advocating regime change.

The extent to which Israeli pressure shaped successive American policies is a question historians and investigative journalists will continue to debate.

Yet responsibility for the breakdown cannot be placed on Washington and Jerusalem alone. Iranian leaders contributed significantly to making the conflict with the United States so intractable.

A corrupt, repressive and economically struggling regime relied heavily on performative anti-American politics for domestic legitimacy. Tehran matched American and Israeli rigidity with intransigence and strategic overreach of its own.

Limiting inspections by the International Atomic Energy Agency, failing to provide credible answers about past nuclear activities, constructing secret facilities and attempting to negotiate from a position of weakness ultimately proved disastrous when dealing with an impatient and impulsive American president.

The unknown unknowns

What comes next?

If regime change does not occur in Tehran, the two sides will almost certainly find themselves negotiating again once the fog of war dissipates.

The hostility between them will not disappear, and diplomatic niceties may become rarer. Yet diplomacy rarely requires trust; it requires interests.

I believe that future talks are therefore likely to be transactional rather than transformational. Technical and legal parameters will still need to be negotiated. Hawks and doves will continue to compete for influence in both capitals.

And the oldest rule of bargaining will remain unchanged: When you lack leverage, acquire it – then negotiate.
