Iran has firmly rejected the possibility of suspending uranium enrichment in any nuclear deal with the United States, a core demand from Washington amidst ongoing negotiations that began in April. The talks, which represent the highest-level contact since the U.S. exited the 2015 nuclear accord, have been described by Trump as “very, very good,” while Iran’s foreign minister labeled them “complicated.” As Iran continues to enrich uranium beyond the accord’s limits, Western nations express concerns over its potential nuclear weapons ambitions, which Tehran denies.
