U.S. Intelligence Says Iran’s New Supreme Leader Is More Open to the Bomb — and Trump Talks ‘Massive Attack’
U.S. intelligence agencies now judge that Iran’s new supreme leader, Ayatollah Mojtaba Khamenei, is more willing than his father to pursue a nuclear weapon, even as Tehran has not formally restarted its weapons program. At the same time, Donald Trump is weighing a ‘massive attack’ on Iran and claims Washington is ‘winning the war by a lot,’ raising the prospect that nuclear risk and military risk could climb together. This story unpacks the intelligence assessment, Trump’s options, and what a harder Iranian nuclear line means for Israel, the Gulf and global nonproliferation.
When the person who controls Iran’s nuclear file changes, the risk calculus for an entire region changes with him. U.S. intelligence agencies now believe Ayatollah Mojtaba Khamenei, who has succeeded his father as Iran’s supreme leader, is significantly more willing to pursue a nuclear weapon than Ali Khamenei was—at the very moment Donald Trump is threatening what he calls a “massive attack” on the country.
Officials briefed on the assessment say the new leadership in Tehran appears more open to developing advanced nuclear capabilities that could shorten the path to a bomb. They emphasize that Iran has not resumed an active weapons program, but the shift in intent, as seen from Washington, is stark. Where Ali Khamenei is understood to have maintained a long-standing religious and strategic objection to crossing the nuclear threshold, Mojtaba is seen as more pragmatic and more ready to treat nuclear arms as an option rather than a taboo.
Trump is publicly responding with both pressure and ambiguity. In an interview published on 24 July, he told an American outlet he is considering a “massive attack” on Iran, “bigger than ever before,” while advisers reportedly met him on Friday to discuss expanding U.S. military action. He has also said the United States is “winning the war by a lot,” that Iran is “not a great power anymore,” and that Washington is “locked and loaded,” even as he insists there are “many exit strategies” and ongoing talks with Tehran.
On the record, Trump describes two paths: “We can take them apart piece by piece, or we can negotiate with them,” he said, adding that Iranian officials “want to make a deal” but sometimes posture as “tough guys.” At the same time, he has refused to say whether bombing civilian infrastructure in Iran would constitute a war crime, brushing off a question from a reporter. The combination of confident rhetoric, undefined red lines and an intelligence picture of a more nuclear-ambitious adversary is exactly the kind of mix that has worried nonproliferation experts for years.
For ordinary Iranians, the stakes are immediate. A leadership that appears more open to nuclear weapons and more exposed to U.S. military action increases the risk that sanctions tighten further, foreign investment dries up and critical infrastructure becomes a target. For civilians in Gulf states, Israel and beyond, the danger is that miscalculation turns their cities, ports and air bases into potential missile aim points in a confrontation framed around nuclear risk.
Strategically, the assessment about Mojtaba Khamenei lands in a Middle East already fraying under multiple pressures: reported U.S. strikes on Iranian territory, moves to build an international maritime coalition in the Strait of Hormuz, and Trump’s effort to tie a Saudi nuclear deal to the Abraham Accords. Israel, which has long reserved the right to act unilaterally against an Iranian bomb, now faces a leadership in Tehran that Washington believes is readier to cross the line, potentially compressing its own decision timelines.
The nonproliferation regime is under strain elsewhere too. Venezuela has announced its intention to withdraw from the International Criminal Court, and major powers are trading accusations over double standards in enforcing international law. In that context, Iran’s leaders may calculate that developing nuclear capabilities brings deterrent value with lower diplomatic cost than in the past, especially if they perceive that enforcement is uneven and politically driven.
One hard-to-ignore reality emerges from this moment: nuclear risk is rising not because of a single test or treaty withdrawal, but because the people with their hands on the controls are changing—and signaling different priorities. A more nuclear-curious supreme leader in Iran and a U.S. president publicly floating unprecedented strikes is a combination that reduces the margin for error on both sides.
The next markers to watch will be movement in Iran’s enrichment levels and centrifuge deployment, any U.S. or Israeli statements about updated red lines, and whether Trump’s advisers succeed in translating his rhetoric into a defined strategy—or whether policy continues to be made in the space between television interviews and military briefings.
