US Hardens Nuclear Demands in Iran Talks, Extends Enrichment Ban

The United States has escalated its demands on Iran as negotiations intensify, pushing for a 20-year halt on uranium enrichment—double the 10-year period previously discussed. The tougher stance, reported by Fox News, centers on what Washington calls the "bigger battle": dismantling Iran's nuclear program and missile capabilities, with the threat of renewed airstrikes if Tehran refuses.

According to the network, a prominent supporter of President Donald Trump, the new U.S. proposal also bans all underground nuclear activities and requires the dismantling of key nuclear facilities. These conditions were leaked as part of a broader push to secure an agreement that would end hostilities.

Key Points of Contention

The enrichment freeze duration has been a major sticking point. Earlier reports from CNN and Axios indicated Washington initially sought a 10-year halt, demanding Iran ship its stockpile of highly enriched uranium abroad. Axios later cited three sources suggesting a freeze of at least 12 years, with another source estimating 15 years. Fox News now reports the U.S. has raised the demand to 20 years.

Iran has responded cautiously. Foreign Ministry spokesman Esmail Baghaei stated that the 14-point, single-page U.S. proposal is "still under study," adding that Tehran will send its response through Pakistan, the mediator between the two countries.

Iran's Counterproposal

Tehran has put forward its own plan, agreeing to a temporary enrichment halt of five years. In exchange, it demands the lifting of all U.S. sanctions, the release of billions of dollars in frozen assets, and mutual easing of navigation restrictions in the Strait of Hormuz.

Under the U.S. framework, the two sides would enter a 30-day negotiation period after a ceasefire declaration, during which they would address unresolved issues including nuclear matters, unfreezing Iranian assets, and future security in the Strait of Hormuz.

Iran currently holds a stockpile of uranium enriched up to 60%, a level below the 90% threshold required for weapons-grade material.
