How developed was Iran's nuclear program and what's left now?

Before the U.S. joined Iran and Israel's open conflict over the weekend, Israeli intelligence seemed to be at odds with the United States over the true nature of Iran's nuclear capabilities. Israeli Prime Minister Benjamin Netanyahu has been arguing for decades that Iran is on the verge of creating (or already has created) a nuclear weapon, while the U.S. intelligence community has historically downplayed Iran's nuclear threats.

But the U.S. government's opinion on Iran's nuclear program appears to be changing under the second Trump administration, as President Donald Trump seems to be moving toward Netanyahu's stance after diverging from his own intelligence director and launching an attack on Iran's primary nuclear sites, Fordo and Natanz. But while Trump claims Iran's nuclear development has been badly diminished by these attacks, the real extent of the program remains unclear.

What did the commentators say?

Netanyahu initially "ordered the attack on Iran because he believed Tehran was 'marching very quickly' toward a bomb" with nuclear capabilities, but the U.S. intelligence community has "long had a somewhat different interpretation," said NPR. Iran halted its nuclear weapons development in 2003, according to official U.S. intelligence. As a result, international and U.S. intelligence assessments have generally concluded that Iran's nuclear program "isn't currently weaponized," said CNN.

This largely contradicts Israel's intelligence assessments, which "always tended to see new developments in Iran's nuclear program as movement toward a bomb that would directly threaten Israel," said NPR. Iran indeed has "spent decades developing its nuclear program and sees it as a source of national pride and sovereignty," said CNN. But it seems Trump has changed his mind on Iran, as he previously said his "director of national intelligence was 'wrong' when she testified that Iran was not building a nuclear weapon," said Al Jazeera.

Just how developed Iran's program is remains ambiguous. Iran has over 400 kilograms (900 pounds) of uranium enriched at 60%, according to the International Atomic Energy Commission. Most experts say creating a nuclear weapon requires uranium enriched at 90%. If Iran's uranium met this mark, the nation would have "enough material for about 10 nuclear weapons," said NPR.

What next?

As the debate over Iran's capabilities continues, the country remains "less than satisfactory" in several respects "regarding its nuclear cooperation," said the Council on Foreign Relations. With Israel and Iran continuing to bombard each other, the conflict doesn't appear to be slowing down.

While Netanyahu has always been clear on his stance about Iran, Trump has seemingly gone back and forth — until he decided to launch a series of strikes against Iran, making clear his agreement with Netanyahu. The attack targeted Iran's most heavily fortified nuclear site, Fordo, which is buried deep in a mountain and is shrouded in mystery, as well as another nuclear site, Natanz. Trump claimed that the use of American "bunker-busting bombs" on Fordo had "completely and totally obliterated" the site.

But it remains unclear if this is true; there is "little doubt that the sites Tehran has been using to produce highly enriched uranium" have "suffered severe damage" due to U.S. bombing, said the Financial Times. But the "critical question will be whether Iran's program has been destroyed, or simply pushed into smaller, secret facilities." A large portion of Iran's cache of 60% enriched uranium was reportedly being stored at the bombed sites. Whether or not this supply was moved ahead of the bombing has yet to be determined.

It "would be foolish if you said that the program was delayed by anything more than a few months," said Richard Nephew, a former U.S. official who worked in the Obama and Biden administrations, to the Times. But Iranian officials say they remain confident: It would have been "very naive to keep our enriched uranium in those sites. The enriched uranium is untouched now," a source in the Iranian regime said.
