During the G7 Summit in Évian-les-Bains, France, President Donald Trump delivered a stark warning to the Iranian regime on Tuesday. He made it unequivocally clear that Iran would face severe repercussions if it pursued a nuclear weapon by any means.
In an interview with Fox News, Trump was firm and explicit: "Iran will never have a nuclear weapon, and let me be loud and clear: they won't develop it, they won't buy it, they won't do anything with it. And if they try, the consequences will be extraordinary. Not just minor... these are the ultimate consequences."
The president reinforced his stance with a powerful statement: "If they proceed, all hell will rain down upon them, and they will not proceed."
These comments come amid a period of intense diplomatic strain, just two days after Trump announced a preliminary peace agreement with Tehran. This agreement aims to conclude 110 days of conflict that began with Operation Epic Fury on February 28, 2026. This aerial assault, coordinated between the U.S. and Israel, resulted in the elimination of Supreme Leader Ali Khamenei within hours.
Key Negotiation Insights
At the G7, Trump unveiled a crucial detail from the negotiations: the initial draft of the agreement only barred Iran from developing a nuclear weapon. However, Trump insisted on expanding this clause.
"Marco was with me, and initially, they wrote that they wouldn't develop a nuclear weapon. I said: no, no, they won't develop it, and they won't buy it either," he explained, referencing Secretary of State Marco Rubio.
According to Trump, this expansion—which now prohibits Iran from developing, purchasing, or acquiring a nuclear device by any means—required several additional days of negotiation: "That took a couple more days. Everything that sticks is ridiculous, but we got it."
Fragile Peace and Lingering Disputes
The president emphasized that the nuclear red line was his primary motivation for engaging in the process: "I hope we have a very good relationship. But the most important thing is they won't have a nuclear weapon. That's why I got involved and why I agreed to sign."
However, the agreement remains fragile. Iran declared victory after the understanding, with Foreign Minister Abbas Araqchi warning that future negotiations will be "based on distrust, past failures to comply, and previous experiences."
Additionally, a central dispute persists over the duration of the nuclear enrichment moratorium: Washington demands 20 years, while Tehran suggests a range of five to 15 years. The most sensitive issues are deferred to a second negotiation phase.
The price of Brent crude oil fell by 4.6%, reaching $83, following the peace agreement announcement, 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 Friday, June 19, in Switzerland, although the definitive nuclear terms are yet to be finalized.
