The president Donald Trump issued a clear warning to the Iranian regime this Tuesday during the G7 Summit held in Évian-les-Bains, France: if Iran attempts to acquire a nuclear weapon by any means, it will face "ultimate consequences."
In statements collected by Fox News from the G7, Trump was emphatic: «Iran will never have a nuclear weapon, and I say this loud and clear: they will not develop it, they will not buy it, they will not do anything with it. And if they do, they will face unbelievable consequences. Not just a little... the consequences are the ultimate consequences».
The leader concluded his warning with a phrase that summarizes his position: «If they do it, all hell will break loose on them, and they won't do it».
The statements come at a time of extreme diplomatic tension, just two days after Trump announced a preliminary peace agreement with Tehran that would bring an end to 110 days of war that began with Operation Epic Fury on February 28, 2026, a coordinated air offensive between the U.S. and Israel that eliminated the Supreme Leader Ali Khamenei in its early hours.
Trump also revealed a key detail of the negotiations at the G7: the initial wording of the agreement only prohibited Iran from developing a nuclear weapon, but he himself demanded that this clause be expanded.
“Marco was with me, and they originally wrote that they would not develop a nuclear weapon. I said: no, no, no, they are not going to develop it and they are not going to buy it either,” he explained, referring to Secretary of State Marco Rubio.
According to Trump, this expansion—which now prohibits Iran from developing, buying, or acquiring a nuclear device by any means—required several additional days of negotiation: "That took a couple more days. Everything that gets stuck is ridiculous, but we have it."
The president emphasized that the nuclear red line was his primary motivation for getting involved in the process: "I hope we have a very good relationship. But the most important thing is that they will not have a nuclear weapon. That is the reason I got involved and why I agreed to sign."
The agreement, however, remains fragile. Iran declared victory following the understanding, and its Foreign Minister Abbas Araqchi warned that future negotiations will proceed "on the basis of distrust, past breaches of commitments, and previous experiences."
There is also a persistent central dispute regarding the duration of the moratorium on nuclear enrichment: Washington demands 20 years, while Tehran proposes between five and 15. The more sensitive issues are deferred to a second phase of negotiations.
The price of Brent oil dropped by 4.6%, down to 83 dollars, following the announcement of the peace agreement, reflecting the global impact of a conflict that included the closure of the Strait of Hormuz —through which 20% of the world's oil passes— for weeks.
The formal signing of the memorandum of understanding is scheduled for next Friday, June 19th, in Switzerland, although the final nuclear terms are not yet finalized.
