Iran Offers to Pause Nuclear Activity for up to 5 Years as Talks with US Hit Impasse
Published on Reflecto News | World News | Nuclear Diplomacy & Geopolitics
Iran has formally proposed to suspend its nuclear activities for up to five years, a significant concession aimed at breaking the deadlock in negotiations with the United States. However, the offer falls far short of Washington’s demand for a 20-year halt, leaving the two sides at a critical impasse as the fragile ceasefire hangs in the balance .
According to a report by The New York Times citing officials from both countries, the United States presented a demand for a 20-year suspension of Iran’s uranium enrichment activities during the weekend talks in Islamabad. In response, Iran delivered a formal counter-proposal on Monday, offering a pause of one-fourth of that duration — up to five years .
The Nuclear Sticking Point
The disagreement over the timeline for suspending enrichment has become the central obstacle in the negotiations. The U.S. position, shaped by Vice President JD Vance, calls for a suspension of about 20 years as necessary to permanently limit Iran’s nuclear capabilities .
President Donald Trump has backed this tougher stance, aligning with Vance’s push for longer-term restrictions. On Monday, Trump told reporters at the White House that his administration had received a call from Iran indicating they “would like to make a deal very badly,” but he reiterated that he will not accept any agreement allowing Iran to possess nuclear weapons .
“Iran will never have a nuclear weapon. If they don’t agree, then there is no deal. There will never be a deal.” — President Donald Trump
Enriched Uranium Stockpile Dispute
Beyond the timeline for suspending activity, the two sides are also at odds over what to do with Iran’s existing stockpile of enriched uranium. The United States has demanded that all highly enriched uranium be shipped out of Iran .
Iran has resisted this demand, insisting that the nuclear material remain inside the country. However, as a compromise, Tehran has offered to “significantly” dilute its existing stockpiles — a proposal that would reduce the purity of the material but keep it within Iran’s borders .
Other Outstanding Issues
The nuclear dispute is not the only issue looming over the negotiations. Other key sticking points include:
- Strait of Hormuz: Restoring free passage through the strategic waterway, which Iran has effectively closed to much international shipping since the war began.
- Regional proxies: Ending Iran’s support for proxy groups including Hamas, Hezbollah, and the Houthis.
- Sanctions relief: Iran demands the complete lifting of all sanctions, while the U.S. has offered only phased relief tied to compliance .
Diplomatic Path Remains Open
Despite the wide gap, the fact that both sides are now negotiating specific timelines — rather than debating the principle of suspension itself — suggests there may still be room for a deal. Officials told The New York Times that another round of in-person negotiations is being discussed, though no dates have been finalized .
Vice President Vance, who led the U.S. delegation in Islamabad, said there had been “some good conversations” with Iranian negotiators, adding that “the ball is now in Tehran’s court” . When asked about additional talks in the coming days, Vance said the question would be “best put to the Iranians” .

The talks are unfolding against a backdrop of escalating military pressure. On Monday, the United States began a naval blockade of Iranian ports, a move aimed at cutting off Iran’s oil exports and forcing Tehran back to the negotiating table . Iran has responded sharply, with the Revolutionary Guards warning that any approach by military vessels toward the Strait of Hormuz will be considered a breach of the ceasefire .
What Comes Next
Trump has made clear that another U.S. priority is the physical retrieval of Iran’s enriched uranium. “We’re going to get the (uranium) dust back. We’ll get it back. Either we’ll get it back from them or we’ll take it,” Trump reiterated .
| Position | Enrichment Halt | Stockpile | Proxies | Strait of Hormuz |
|---|---|---|---|---|
| United States | 20 years | Ship out of Iran | End support | Immediate, full reopening |
| Iran | 5 years | Keep, but dilute | Non-negotiable | After final peace agreement |
The two-week ceasefire, brokered by Pakistan and announced on April 7, remains in effect but is increasingly fragile. With the U.S. naval blockade now in place and both sides hardening their positions, the window for a diplomatic breakthrough is narrowing. Yet the exchange of specific proposals — a 20-year U.S. demand versus a 5-year Iranian counter-offer — suggests that for the first time in weeks, the outlines of a potential deal are visible, even if the distance between them remains vast.
