Yellow, blunt-nosed, and roughly the size of a compact car. That is the first thing that struck me, standing before the replica of Fat Man in the Nagasaki Atomic Bomb Museum. It did not look like something that should, by any logic of proportion, have the destructive power to annihilate a city.

On August 9, 1945, at 11:02 in the morning, Fat Man detonated above Nagasaki. By the year’s end, 90,000 people were gone. The museum is quiet in the way that only certain places are quiet — not the absence of noise, but the presence of something heavier. I moved from exhibit to exhibit and the numbers stopped being numbers. They became faces. Schoolbags. A melted glass bottle infused with skeletal remains. A wristwatch stopped forever at 11:02. One survivor, Reiko Hada, was nine years old when the bomb fell. She spent the rest of her life carrying the weight of that morning. “Many hibakusha died without being able to talk about their sufferings,” she said. “They could not speak, so I speak.”

I left the museum thinking about Iran.

Not because the historical parallels are clean — they are not. But because standing before that replica of an atomic bomb, I understood viscerally what the debate about Iran’s nuclear program is actually about. It is not a policy debate. It is not a diplomatic chess match. It is about whether a weapon capable of producing another Nagasaki ends up in the hands of a regime that has demonstrated, repeatedly and without ambiguity, that it does not behave like a state that rationally calculates consequences.

The standard deterrence argument goes like this: Israel is widely understood to possess its own nuclear arsenal. Iran knows this. Therefore, launching a nuclear strike against Israel would invite annihilation — Mutually Assured Destruction, MAD. Whatever their rhetoric, those in power in Tehran are ultimately self-preserving pragmatists.

I do not find this convincing.

MAD works only when both parties want to survive. It is a doctrine built entirely on the assumption of rational actors — governments that, however hostile, shrink from their own extinction. But we do not need to speculate about the psychology of any individual Iranian leader. We can read intentions from actions. A regime that has spent decades funding proxies across the region, that has struck neighbours from Azerbaijan to the UAE to NATO members Turkey and Cyprus, that has killed its own people in the streets for demanding basic freedoms — that regime has told us everything we need to know about how it weighs consequences. Though we do not know exactly who is giving the orders in Tehran today, we know what those orders have produced.

And then there is the Iron Dome. Israel’s air defence system is, by any measure, a remarkable achievement — a shield that has saved countless lives. But no shield is perfect. We have seen this with our own eyes, as missiles and drones have penetrated Israeli airspace under conventional attack. 

Against a conventional salvo, an imperfect shield means property damage — perhaps an apartment complex is struck. There may be a few casualties.

Against a nuclear salvo — multiple warheads launched simultaneously — an imperfect shield means one gets through.

Tel Aviv might be gone. Hundreds of thousands of people, dead in a morning. 

Consider what has already happened. Iran’s navy and air force have been destroyed. Thousands of military targets have been eliminated. Its supreme leader is dead, along with senior commanders across the IRGC and intelligence services. Its cities have been bombed and its economy strangled. 

Pakistan brought both sides to the negotiating table in Islamabad — the highest-level engagement between Washington and Tehran since 1979. Twenty-one hours of negotiation, with Pakistani officials mediating between the delegations. No deal was struck. President Trump himself said that most points were agreed upon — but “the only point that really mattered, NUCLEAR, was not.” Iran refused to give up its pursuit of nuclear weapons. 

A regime that absorbs all of that — and still will not surrender its pursuit of the bomb — is not making a rational calculation about survival. It is telling us, with unmistakable clarity, what it values most.

The Nagasaki Atomic Bomb Museum exists so that the world does not forget what a single weapon did to a single city on a single morning. It is a place of mourning, and of warning. We do not need another one. 

We especially do not need one in Tel Aviv.
