At White House press secretary Karoline Leavitt’s latest briefing, the president’s chief spokesperson said Donald Trump will decide within “two weeks” whether to launch a U.S. military offensive against Iran. One reporter asked whether the president is relying on U.S. intelligence as part of the decision-making process.

Leavitt responded that it’s a “fact” that Iran is very close to having a nuclear weapon, adding that the U.S. government “maintains this fact that Iran has never been closer to obtaining a nuclear weapon.”

There are, however, some notable nuances to this. As NBC News reported this week, “The U.S. assessment of Iran’s nuclear program has not changed since March, when the director of national intelligence told lawmakers that Tehran has large amounts of enriched uranium but has not made a decision to rush toward building an atomic bomb, according to the top Democrat on the Senate Intelligence Committee and a source with knowledge of the matter.”

That might not be what the White House wants the public to hear, but it’s what U.S. intelligence agencies keep telling policymakers.

But as critically important as that intelligence is, Leavitt’s claims led to a related question: If it’s true that Iran has never been this close to obtaining a nuclear weapon, maybe it’s worth having a public conversation about why Tehran has become more dangerous?

Trump spent much of the 2024 election cycle claiming he’d nearly completed a nuclear agreement with Iran but ran out of time before leaving the White House in early 2021. Those claims were difficult to believe, but just as notably, they overlooked a key detail: Iran had already reached a nuclear agreement with the U.S. — during Barack Obama’s second term. It was called the Joint Comprehensive Plan of Action (JCPOA), and it came to be known as the Iran nuclear deal.

As regular readers know, the international agreement with Iran did exactly what it set out to do: The policy dramatically curtailed Tehran’s nuclear ambitions and established a rigorous system of monitoring and verification. Once the policy took effect, each of the parties agreed that the participants were holding up their end of the bargain, and Iran’s nuclear program was, at the time, on indefinite hold.

And then Trump took office and abandoned the policy for reasons he never explained.

In broad strokes, Obama set out to use economic sanctions to get Iran to the international negotiating table. That worked and a breakthrough agreement eventually followed. Trump came to believe he could duplicate the strategy by abandoning the policy, restoring the old sanctions and adding new ones.

This was known as the Republican’s “maximum pressure” campaign, and it was pursued on the assumption that Iran would inevitably return to the negotiating table. If Obama’s sanctions led to a landmark deal, the argument went, then maybe Trump’s sanctions could produce an even better deal.

That didn’t happen. Trump’s approach failed.

In fact, once the U.S. was no longer a part of the agreement, the West lost verification access to Tehran’s program. It was at that point that Iran, rather than begging the White House for attention, almost immediately became more dangerous by starting up advanced centrifuges and ending its commitment to limit enrichment of uranium.

Trump wants to declare ‘Mission Accomplished’ on Iran. Not so fast.

Zeeshan Aleem

A couple of years ago, Robert Malley, the then-special envoy for Iran, told the Senate Foreign Relations Committee that after Trump’s decision, Iranian attacks on U.S. personnel in the region got worse, Iranian support for regional proxies got worse, and the pace of the Iranians’ nuclear research program got “much worse.”

How Trump arrived at his decision adds insult to injury. One of my favorite stories about the Iran deal came a few months into Trump’s term in the White House, when the president held a lengthy meeting with top members of his team: Secretary of State Rex Tillerson, Defense Secretary James Mattis, White House National Security Adviser H. R. McMaster and Chairman of the Joint Chiefs of Staff Gen. Joseph Dunford. Each of the officials reportedly told Trump the same thing: It was in the United States’ interest to preserve the JCPOA policy.

The Republican expected his team to tell him how to get out of the international agreement, not how to stick with it. When his own foreign policy and national security advisers told him the policy was working, Trump reportedly “had a bit of a meltdown.”

Soon after, he abandoned the JCPOA anyway — not because it was failing, but because Trump was indifferent to its success.

All Trump had to do was nothing. He could’ve simply left the policy alone and allowed it to keep working. He instead did the opposite. The Republican was convinced his strategy would work — he even boasted at one point during his term that he was prepared to be Iran’s “best friend” — but the entire gambit backfired.

Seven years later, Trump and his team want to talk about how dangerous Iran is. What they don’t want to talk about is how much the president’s own misjudgment made the Iranian threat worse.
