Trump’s Hormuz Threats Jolt US–Iran Talks and Raise Escalation Risk
High‑stakes talks between US and Iranian officials in Switzerland have been shaken by Donald Trump’s public threats to “erase” Iran if it shuts the Strait of Hormuz and to hit the country “harder” over Hezbollah. Iranian negotiators briefly walked out and warned they will halt all discussions unless Israel withdraws from Lebanon and a ceasefire holds across the region, putting energy flows and regional war‑end diplomacy on the line.
Diplomacy meant to dial down a Middle East war is now itself a source of risk. High‑level talks between the United States and Iran in Switzerland, billed as a chance to move from a memorandum of understanding toward a broader settlement, have been shaken by a barrage of public threats from US President Donald Trump over the Strait of Hormuz and Iran‑backed forces in Lebanon.
Trump told Fox News that if Iran closes the Strait of Hormuz, “their country will be erased” and said the United States could seize control of the waterway. On social media he warned that unless Tehran reins in its “highly paid proxies in Lebanon,” Washington would strike Iran “very hard again, just like we did last week, only harder.” In a separate account of remarks to Iranian negotiators in Switzerland, Trump is quoted as saying that if Iran closes the strait, “you won’t have a country” and that the United States could “seize the strait if necessary.”
Iranian media aligned with the negotiating team reported that Tehran has formally protested Trump’s statements as a violation of the first clause of the existing memorandum, which they say obliges the United States to refrain from threats. Those outlets, citing informed sources and members of the delegation, said the Iranian side left the venue after roughly 80 minutes of talks in protest and that discussions would not resume unless Israel withdraws from Lebanon and a ceasefire is reached on all fronts.
Other accounts, including a report attributed to journalist Barak Ravid, said the talks had not fully collapsed and were continuing. What is clear from both sides, however, is that Tehran is tying any broader agenda—including nuclear and sanctions issues—to the war in Lebanon and to Israeli military posture there, and that the first round of the Swiss meeting was dominated by Lebanon rather than nuclear terms.
The stakes are immediate for civilians across the region. For Lebanese residents caught between Israeli military operations and Hezbollah’s escalation, Iran’s decision to condition diplomacy on a ceasefire and withdrawal translates into whether artillery batteries pull back or remain in range of towns and villages. For families in Iran still grieving reported US and Israeli strikes, including on a primary school in Minab, Trump’s language about “erasing” the country is more than rhetoric—it is heard against a backdrop of fresh casualties and a sense that negotiations could either stop further attacks or entrench a harsher confrontation.
Operationally, Trump’s threats focus attention on one of the world’s most sensitive maritime chokepoints. Hormuz handles a significant share of global seaborne oil exports; even partial disruption would hit tanker crews, insurers and energy buyers far beyond the Gulf. Iranian officials and allies are now openly framing the strait as bargaining leverage. Hezbollah’s deputy leader, Naim Qassem, praised Iran for allegedly closing Hormuz “in support of Lebanon,” presenting it as a model for how Beirut should negotiate, though such claims are politically charged and not independently confirmed.
Tehran, for its part, says a draft has been finalized for waivers on US oil sanctions, with issuance expected soon, even as it warns that talks on additional issues will not move without an end to the war in Lebanon. That combination—preparing to expand oil exports while threatening to walk away from the table—puts pressure on both energy markets and US policy planners. Republican Senator Lindsey Graham, after meeting Trump, publicly floated the idea that if diplomacy fails, Washington could take control of Hormuz and charge a fee for shipping, underscoring how quickly the conversation is drifting from de‑escalation into coercive scenarios around a global artery.
The broader pattern is of a negotiation process that has pulled the Lebanese battlefield and the world’s key oil lane into the same argument. Iranian parliamentary speaker Mohammad Ghalibaf, who heads the delegation, has dismissed American threats as signs of “desperation” and warned that Iran’s armed forces are prepared to respond “in a different way,” while reiterating that there will be no talks on other topics until Lebanon is addressed. For both governments, the question is no longer whether the Hormuz card will be played, but how close each side is willing to edge to testing it in practice.
Hormuz risk does not require a full blockade to matter—only enough credible uncertainty to make shipowners and governments hesitate. That is what this round of brinkmanship has begun to create: a cloud over energy flows, an added layer of fear for crews transiting the Gulf, and higher political costs for any leader seen as conceding under pressure.
The next signals to watch are whether Iran’s negotiating team physically returns to the Swiss venue for another round, how Washington responds to Tehran’s formal protest over Trump’s remarks, and whether any language on Israeli withdrawals or a Lebanon ceasefire makes it into a written understanding. Any visible change in US naval posture near Hormuz, or in Iran’s messaging about the strait and Hezbollah’s operations, will show whether the threats are hardening into a new phase of confrontation or being walked back into a fragile bargain.
