JD Vance Sees Progress, Trump Issues Threat: Are US-Iran Talks Really Working?

Even as diplomatic talks between the United States and Iran continue in Switzerland, US President Donald Trump has issued a fresh warning to Tehran, signalling that tensions between the two countries remain far from resolved.

Trump said Iran must immediately rein in its regional allies, particularly Hezbollah in Lebanon, or face stronger military action from the United States. His remarks came just as US Vice President JD Vance reported progress in discussions aimed at improving relations between Washington and Tehran.

Trump Issues Fresh Threat to Iran

In a post on Truth Social, Trump warned that Iran would face severe consequences if Hezbollah continued activities that Washington views as destabilising.

"Iran must immediately stop their highly paid proxies in Lebanon from causing trouble. If they don't, we'll hit Iran very hard again, just like we did last week, only harder," Trump wrote.

The statement highlights the delicate situation facing negotiators, who are attempting to build trust while dealing with deep disagreements over regional security issues.

US-Iran Agreement Not Yet Final

Trump also stressed that the recently signed memorandum of understanding (MoU) between the United States and Iran should not be viewed as a final peace agreement.
Speaking to reporters during the G7 Summit in France alongside Egyptian President Abdel Fattah el-Sisi, Trump said the agreement remains conditional on Iran's future conduct.

According to Trump, if Iran fails to comply with expectations or if the final terms of the agreement are not satisfactory, the United States could return to military action.
"It's not final. It's a memorandum of understanding," Trump said, adding that Washington would not hesitate to resume strikes if Tehran failed to "behave."

Talks Continue in Switzerland

The latest diplomatic push follows an agreement reached earlier this week between Trump and Iranian President Masoud Pezeshkian aimed at ending a conflict that lasted more than three months.

The understanding reportedly includes efforts to maintain stability in the Strait of Hormuz, one of the world's most important shipping routes through which nearly one-fifth of global oil supplies pass.

Negotiations currently underway in Switzerland are expected to focus on long-term security arrangements, regional tensions, and Iran's nuclear programme.

Vice President JD Vance, who is leading the American delegation, recently described the talks as productive and said there had been positive developments on several issues.

Democrats Demand Details of Agreement

While the administration has highlighted the diplomatic breakthrough, senior Democratic lawmakers have demanded greater transparency regarding the agreement.

Congressmen Gregory Meeks, Jim Himes and Adam Smith have written to US Secretary of State Marco Rubio seeking an immediate briefing on the memorandum.

The lawmakers said Congress needs a clearer understanding of the agreement, including any side arrangements and the administration's strategy during the 60-day ceasefire period.

In their letter, they welcomed the move towards diplomacy but argued that lawmakers must be informed about the details before further decisions are taken.

Uncertain Road Ahead

The latest developments reflect the complicated nature of US-Iran relations. On one hand, negotiations are progressing and both sides have agreed to continue diplomatic engagement. On the other, public warnings from Trump and continuing disagreements over regional issues show that significant obstacles remain.

As talks continue in Switzerland, the world will be watching closely to see whether diplomacy can produce a lasting agreement or whether tensions between Washington and Tehran once again move towards confrontation.
