Merz Says Iran Is Humiliating the US as Nuclear Talks Falter

Friedrich Merz, Germany's newly installed chancellor, delivered an unusually blunt assessment of the state of nuclear diplomacy with Iran on 27 April 2026, telling reporters in Berlin that Tehran was "humiliating" the United States as talks over its nuclear programme appeared to stall for the first time since they resumed.

The comments, made at a joint press conference with European Commission President Ursula von der Leyen, mark a notable hardening in the German government's tone toward Iran. Merz, who took office in March after a fractious coalition formation, has signalled a more transactional approach to foreign policy than his predecessor. The directness of his language — "humiliating" is not a word chancellors typically deploy in public about a negotiating partner — reflects the depth of frustration inside the German foreign policy establishment.

The State of the Talks

The nuclear negotiations, conducted through intermediaries and occasionally directly in Oman and Qatar, have been ongoing since early 2025. The broad framework under discussion is a return to the 2015 Joint Comprehensive Plan of Action, the nuclear agreement that former President Trump abandoned in 2018, with附加条件 designed to address concerns about the scope of Tehran's enrichment programme and the duration of any lifted sanctions.

But three rounds of talks in recent months have produced no joint statement, no agreed agenda, and increasingly divergent accounts of what each side is prepared to accept. According to accounts from diplomatic observers familiar with the discussions, Iran has insisted on a guaranteed timeline for sanctions relief and a formal end to the "maximum pressure" campaign before any additional constraints on enrichment are discussed. The US position, as articulated by State Department officials, requires verified cuts to Iran's enriched uranium stockpile and the closing of advanced centrifuge facilities before sanctions are eased.

The gap between those positions is not new. What has changed, several European diplomats suggested in background comments to wire services, is the sense that Iran has begun testing whether the Trump administration's stated preference for a deal is durable, or whether the threat of military action can be used as leverage to extract better terms. That testing, in Merz's framing, has crossed into something that damages Washington's standing.

European Divisions on Approach

Merz's intervention sits uneasily with some of Germany's European partners. France and the United Kingdom have been more measured in their public language, preferring to characterise the talks as "difficult but not dead." The distinction matters because Germany, France, and Britain — the so-called E3 — have been co-signatories to every version of the nuclear agreement and have a direct interest in preserving a diplomatic track that keeps the Americans and the Iranians in the same room.

The deeper tension is about what leverage Europeans actually have. Since the US withdrew from the JCPOA, European companies have been largely barred from meaningful commercial engagement with Iran by the re-imposition of secondary sanctions. The diplomatic value the E3 brings is therefore primarily symbolic and procedural — hosting talks, shuttling messages, providing cover for direct US-Iranian contact. If the Americans and Iranians have stopped talking, Europe's role shrinks further.

Iran, for its part, has made clear through state-aligned media that it views European involvement as contingent rather than essential. "The Europeans come to listen more than to speak," one Iranian Foreign Ministry spokesperson said in a briefing carried by Tasnim News Agency. "That is understood in Tehran."

The Structural Problem

What Merz has diagnosed — if not named — is a structural problem that has haunted nuclear diplomacy with Iran since 2018. The agreement worked, however imperfectly, because it was multilateral: the US, the E3, Russia, China, and Iran all had standing stakes that made defection costly. The US withdrawal destroyed that equilibrium. The subsequent "maximum pressure" campaign, combined with Iran's own decisions to exceed JCPOA enrichment limits, has left the parties further apart than at any point in the last decade.

The humiliation framing, whether Merz intended it or not, also speaks to a calculation inside Tehran that may be distinct from the nuclear question itself. Iranian officials, including Supreme Leader Ayatollah Khamenei, have suggested in recent months that a deal with the United States is not inherently desirable — that the cost of appearing to capitulate to American demands could be as destabilising domestically as the sanctions themselves. If that calculation is driving Iranian tactics, then more pressure may not produce movement; it may produce a more hardened negotiating position designed to demonstrate strength rather than seek compromise.

What Comes Next

The immediate question is whether the talks resume at all. The Omani intermediary channel remains open, according to diplomats who spoke to Reuters, but no date for a fourth round has been set. The Americans have not publicly characterised the process as failed, which leaves room — however narrow — for a diplomatic off-ramp.

Germany's position matters in that calculation. As Europe's largest economy and a country with significant commercial interests in any future Iran engagement, Berlin has both the incentive and the instruments to keep the Europeans invested in the process. Merz's public ultimatum, if that is what it is, could be designed to pressure Iran into returning to the table — or it could be a signal that Berlin is preparing to align more closely with Washington in the event that the diplomatic track closes entirely.

What is clear is that the window for a deal before Iran's nuclear programme advances further has not yet closed. But it is narrower than it was a year ago, and the political space for European mediation is narrower with it.
