PARIS/DUBAI, April 19 (Reuters) - European allies fear an inexperienced U.S. negotiating team is pushing for a swift, headline‑grabbing framework deal with Iran that could entrench rather than resolve deeper problems, diplomats with past experience dealing with Tehran said.
They worry Washington, eager to claim a diplomatic win for President Donald Trump, could lock in a superficial agreement on Iran’s nuclear programme and sanctions relief, then struggle through months or years of technically complex follow‑on talks.
"The concern isn’t that there won’t be an agreement,” said a senior European diplomat, one of eight who spoke to Reuters who have previously worked on the nuclear file or continue to do so. "It's that there will be a bad initial agreement that creates endless downstream problems.”
Responding to a series of questions from Reuters, ranging from negotiating style and team to objectives and the potential dangers of a quick deal, the White House rejected the criticism.
"President Trump has a proven track record of achieving good deals on behalf of the United States and the American people, and he will only accept one that puts America first," spokeswoman Anna Kelly said.
Diplomats from France, Britain and Germany — which began negotiating with Iran in 2003 — say they have been sidelined.
From 2013 to 2015, the three worked with the United States to secure a deal on curbing Iran’s nuclear programme in exchange for sanctions relief, known as the Joint Comprehensive Plan of Action.
Trump withdrew from the accord - the signature foreign policy agreement of his predecessor Barack Obama - in 2018, during his first term, calling it "horribly one-sided".
After 40 days of airstrikes, U.S. and Iranian negotiators opened talks in Islamabad earlier this month, again focused on the familiar trade‑off of nuclear restrictions for economic relief. There were some signs in the Pakistani capital on Sunday of preparations for a resumption of face-to-face negotiations.
Diplomats say deep mistrust and sharply different negotiating styles raise the risk of a fragile framework neither side can sustain politically.
"It took us 12 years and immense technical work,” said Federica Mogherini, who coordinated the talks from 2013 to 2015. "Does anyone seriously think this can be done in 21 hours?"
The diplomats said a skeletal agreement may be achievable, built around a nuclear package and an economic package. But they warned the nuclear component remained by far the most contentious.
"The Americans think you agree on three or four points in a five‑page document and that's it, but on the nuclear file, every clause opens the door to a dozen more disputes," a second European diplomat said.
Talks are focusing on Iran's stockpile of roughly 440 kilograms (970 pounds) of uranium enriched to 60%, material that could be used for several nuclear weapons if further enriched.
The favoured option is "downblending" inside Iran under International Atomic Energy Agency supervision. Another is a hybrid approach, with some material shipped abroad.
Turkey and France have been mentioned as possible destinations. Shipping material to the United States would be politically difficult for Iran, while Russia is unattractive to Washington, two of the diplomats said.
Even those options would require lengthy negotiations over recovering material possibly buried by airstrikes, verifying quantities and transporting it securely.
Iran has also floated storing material abroad for a fixed period.
"Whatever happens now is only a starting point,” said a Western diplomat previously involved in nuclear talks. "That’s why the 2015 JCPOA ran to 160 pages."
Beyond stockpiles lies the deeper dispute over Iran’s right to enrich uranium at all. Trump has publicly pushed for zero enrichment, while Iran insists it has the right to enrich uranium for civilian purposes and denies seeking a bomb.
One possible compromise would be a temporary moratorium followed by resumption at very low levels under strict conditions.
Europeans stressed that a central role for the IAEA, including intrusive verification and unrestricted access, was essential.
"A negotiation with Iran is meticulous and subtle: every word matters," said Gérard Araud, France’s chief negotiator from 2006 to 2009. “That’s not something you rush.”
The economic track focuses on lifting sanctions and unfreezing Iranian assets.
In the short term, Iran wants access to limited frozen funds overseas. Broader sanctions relief would come later and require European buy‑in, diplomats said, as Iranian leaders see European trade as critical over the long term.
Officials say Washington is again separating an agreement in principle from its painstaking follow‑up, an approach they say risks misreading Iranian political culture.
"These talks aren't a real‑estate deal settled with a handshake,” said a senior regional diplomat briefed by Tehran, referring to the background of Trump's main negotiators Steve Witkoff and Jared Kushner. "They involve sequencing, sanctions relief and reciprocal nuclear steps.”
The war has hardened Iran’s stance, diplomats said, showing it can absorb pressure even as it seeks financial relief.
Tehran’s top demand is a non‑aggression guarantee after being attacked by the U.S. and Israel during earlier diplomatic efforts.
The concern is shared among U.S. allies. Gulf states want Iran’s ballistic missiles and proxy activities addressed, while Israel is pushing for maximal constraints.
Iran, by contrast, sees its remaining missile capability as a vital deterrent after the war degrad
They fear a hasty agreement could entrench existing problems, leading to ongoing technical disputes and political fragility.
The primary dispute centers on Iran's uranium stockpile, enrichment rights, and how to securely store or dispose of enriched uranium.
Diplomats note that the 2015 deal involved years of technical work, while the current push is for a brief framework lacking detailed provisions.
Negotiations must address technical issues like verifying and securely transporting uranium, especially after airstrikes disrupted stockpile locations.
Sanctions relief is linked to Iran scaling back its nuclear program, but diplomats fear a superficial agreement may complicate effective implementation.
