There has always been a fair and symmetrical formula for the United States and Iran to resolve the full range of their differences: full normalization for full normalization. Donald Trump, who may — but probably doesn’t — want a war with the Islamic republic , should propose it, publicly and in detail, and see what happens.

It will be clarifying for everyone.

What is normalization? From the U.S. side, it would mean the immediate suspension of every economic and diplomatic sanction imposed by this or previous administrations. It would mean an American Embassy in Tehran and an Iranian one in Washington. It would mean direct flights between Iranian and American cities. It would mean two-way trade, direct investment, and the end of secondary sanctions that punish non-U.S. companies for doing business in Iran. It would mean tens of thousands of Iranian students once again enrolled in U.S. universities, and tens of thousands of American tourists once again exploring the grand bazaars of Iranian cities.

Iran’s people could surely use that deal. Since Trump reimposed U.S. sanctions last year, Iran’s oil exports have fallen by more than half, inflation has spiked to close to 40 percent and the rial has lost about 60 percent of its value against the dollar. Iran’s economy is expected to contract by 6 percent this year. By some estimates, a third of all Iranians live in absolute, not relative, poverty, unable to afford the most basic staples of life.

As for the Iranian side, normalization would mean behaving like a normal country.

A normal country, with the world’s fourth-largest proven oil reserves, is one that wouldn’t need to embark on multiple underground programs to enrich uranium and produce plutonium. It wouldn’t engage in extensive experimental work to figure out how to detonate a fissile nuclear core. It wouldn’t retain an illicit network to circumvent Western restrictions on the sale of dual-use technologies for its missile programs.
