U.S. President Donald Trump and senior administration officials have offered conflicting justifications for the renewed U.S. strikes on Iran, including the claim that Iran’s nuclear and missile programs posed an imminent threat to the United States.

But U.S. officials dodged key questions about the nonproliferation obligations Saudi Arabia—a country that has openly threatened to develop nuclear weapons if Iran does—will be subject to under the proposed agreement.
With signals pointing to a resumption of U.S.-Iran talks, the Trump administration has another opportunity to reduce Tehran’s proliferation risk and the likelihood of the United States getting sucked into further, counterproductive military strikes against Iran’s nuclear program. Going into talks, the United States should prioritize restoring IAEA safeguards and move away from unrealistic demands on enrichment.
