U.S. and Iran Move Toward Implementation of Interim Deal Amid Friction Over Nuclear and Maritime Terms
Implementation hurdles and conflicting nuclear claims emerge as the Trump administration prepares for a formal signing ceremony in Switzerland.
The Trump administration and the Iranian government are moving toward the formalization of an interim agreement mediated by Pakistan, with a high-stakes signing ceremony scheduled for June 19 in Switzerland. While the memorandum of understanding has temporarily eased market tensions, both nations are already signaling significant disagreements over the technicalities of the deal. At the center of the friction is the fate of Iran’s highly enriched uranium; U.S. officials claim the deal requires its destruction, while Tehran insists on retaining the stockpile.
The maritime component of the deal also faces immediate challenges. Although President Trump announced the end of the U.S. naval blockade, Iranian Foreign Minister Abbas Araghchi suggested that Tehran may impose service fees on vessels transiting the Strait of Hormuz. Conversely, Vice President JD Vance stated the U.S. expects the waterway to remain open without a toll system, asserting that Washington maintains "all the cards" in ongoing negotiations.
Domestically and regionally, the deal remains fragile. Several Republican lawmakers have criticized the lack of published enforceable language, while Israel has signaled it may not be bound by the cessation of military operations in Lebanon. Analysts warn that the upcoming 60-day negotiation period will be critical in determining whether this memorandum can evolve into a stable treaty or if core regional disputes will cause the framework to collapse.
