US-Iran Negotiations Shift Focus to Uranium Enrichment Restrictions, Strait of Hormuz Emerges as Iran's "Ace in the Hole"

April 21 — The U.S. and Iran are likely to restart negotiations in Islamabad, with signs suggesting Washington may be ready to tolerate Iran’s influence over the Strait of Hormuz to preserve global economic stability. A prior warning from former Russian President Dmitry Medvedev has stoked deep concerns among Gulf states: Reopening the Strait of Hormuz could be the biggest outcome of U.S.-Iran talks, falling far short of the broader de-escalation they seek. Negotiators and analysts expect the upcoming Islamabad round to shift focus away from Iran’s missile program and regional proxy groups, instead centering on restricting uranium enrichment and managing Iran’s control over shipping lanes in the Hormuz oil corridor. This “manage, not dismantle” approach may let Iran tighten its grip on Middle Eastern energy supplies. While prioritizing global economic stability, it sidelines the countries most exposed to energy and security disruptions from the talks. The U.S. and Iran remain deadlocked over uranium enrichment: Iran has rejected demands for “zero enrichment.” Gulf sources note, “Ultimately, the Strait of Hormuz is the final red line — it never was an issue before, but it is now.” Iran’s threats to Gulf shipping have broken a longstanding taboo around controlling the Hormuz Strait, putting lane disruptions on the negotiation table as a tangible bargaining chip for the first time.
