Iran is insisting on its right to uranium enrichment for its civil nuclear program, rejecting the U.S. demand for reliance solely on imported nuclear fuel, leading to a significant negotiating hurdle in ongoing talks. U.S. Secretary of State Marco Rubio proposed a compromise allowing Iran to enrich low-purity uranium under strict inspections, while Iranian negotiator Abbas Araghchi emphasized the need for equal treatment and respect for Iran’s rights as a Nuclear Non-Proliferation Treaty signatory. Concerns remain about the potential for an interim deal that may not fully dismantle Iran’s nuclear capabilities, risking its ability to quickly develop a nuclear weapon.
