For almost half a century, Americans have been told a remarkably simple story: that the United States has been at war with Iran since 1979. It has become one of those political phrases repeated so often that it is rarely questioned. Yet when you actually examine the historical record, the claim begins to fall apart.
The relationship between Washington and Tehran has not been one of continuous war. It has been one of confrontation, cooperation, covert engagement, mutual dependence, proxy conflict, negotiation, and, at times, surprisingly close strategic alignment. It has been complicated, contradictory and often deeply cynical. But it has not been forty-seven years of uninterrupted war.
That distinction matters because false historical narratives lead to bad policy.
The first myth is that the Islamic Republic simply emerged in opposition to the United States. The final years of the Shah’s government were far more complex than the popular story suggests. Washington’s relationship with Mohammad Reza Shah deteriorated dramatically during the revolution, and many critics argue that American policy helped undermine one of its closest regional allies. Whether by design or through miscalculation, the United States did not ultimately preserve the Shah’s rule. The revolutionary government came to power amid a period of extraordinary geopolitical upheaval in which American decisions played an important role.
If America had truly regarded the Islamic Republic as an enemy from day one, the decades that followed become difficult to explain.
Consider the Iran-Contra affair. During the 1980s, while publicly portraying Iran as a hostile state, senior American officials secretly approved arms sales to Tehran. Public rhetoric and private policy were moving in opposite directions. Governments genuinely engaged in existential wars rarely conduct covert weapons deals with their supposed enemy.
The pattern continued.
Throughout the Soviet occupation of Afghanistan, the United States and Iran shared an important strategic objective: forcing Soviet withdrawal. Both countries supported Afghan resistance groups, although often through different channels and with different preferred factions. Their interests overlapped far more than today’s political rhetoric would suggest.
After September 11, that cooperation became even more explicit.
Iran condemned the attacks almost immediately. More importantly, Iranian diplomats and intelligence officials worked closely with the United States during the campaign against the Taliban. Iranian assistance proved valuable during the negotiations that produced Afghanistan’s post-Taliban government, and senior American officials involved at the time have publicly acknowledged Tehran’s constructive role.
That is not the behaviour of two countries locked in an uninterrupted forty-seven-year war.
The same pattern appeared again in Iraq.
Whatever their broader differences, both Washington and Tehran shared an interest in removing Saddam Hussein. After the invasion, both sought to prevent complete state collapse and both invested heavily in stabilising the new Iraqi government, even while competing fiercely for influence inside the country. Cooperation and competition existed simultaneously.
Again, history refuses to fit the simple slogan.
Then came the nuclear negotiations.
The Joint Comprehensive Plan of Action represented years of sustained diplomacy involving American and Iranian officials meeting through both public and private channels. Intelligence cooperation, diplomatic backchannels through Oman and Switzerland, prisoner negotiations, military deconfliction in Iraq and Syria—all demonstrate that communication never truly stopped.
Even during periods of maximum hostility, the two governments continued talking.
None of this means relations were peaceful. They clearly were not.
There were sanctions, assassinations, cyberattacks, proxy wars, military confrontations, hostage crises and enormous mutual distrust. Americans and Iranians have legitimate grievances against one another that cannot simply be dismissed.
But that is precisely the point.
A cold conflict is not the same as a permanent war.
A geopolitical rivalry is not the same as an existential military conflict.
And a relationship containing repeated episodes of strategic cooperation cannot honestly be described as forty-seven years of uninterrupted warfare.
Why, then, has the “forty-seven years of war” narrative become so popular?
Because it simplifies an extraordinarily complicated history into a politically useful slogan. It turns diplomacy into appeasement. It turns negotiation into weakness. It turns every crisis into proof that nothing except confrontation has ever existed.
History says otherwise.
The real story of U.S.-Iran relations is not one of permanent enemies. It is one of governments that have repeatedly found themselves cooperating when their interests aligned and confronting each other when they did not. Sometimes those interests changed within months. Sometimes within days.
That complexity makes for uncomfortable politics, but it makes for far better history.
If policymakers begin with the false assumption that America has been fighting Iran continuously since 1979, then today’s tensions appear inevitable and diplomacy appears futile.
If, instead, they begin with the historical record, they discover something quite different: that despite ideological hostility, both countries have repeatedly demonstrated an ability to cooperate when strategic interests demanded it.
Perhaps the biggest lie is not that America and Iran have disagreed for forty-seven years.
It is the claim that they have never worked together.
History tells a much more interesting story than that.
