Many details in the announced peace deal between the U.S. and Iran still need to be finalized, Vice President JD Vance said Monday morning.

But despite the unresolved issues, Vance projected confidence that the Trump administration enters the next phase of negotiations with overwhelming leverage and a clear path toward preventing Iran from ever obtaining a nuclear weapon.

Appearing on CNBC's "Squawk Box," Vance described the preliminary agreement reached Sunday as a major victory for the United States, one that would immediately reopen the Strait of Hormuz while establishing a framework for permanently ending Iran's nuclear ambitions.

"I think it's a great day for the American people," Vance said. "We have the leverage. We have the diplomatic, economic, and military leverage."

The agreement, which is expected to be formally signed Friday in Geneva, extends the current ceasefire for 60 days while negotiators work through technical details involving sanctions relief, nuclear inspections, enriched uranium stockpiles, and long-term security guarantees.

According to Vance, one of the administration's primary objectives is ensuring that Iran permanently abandons any effort to develop nuclear weapons in exchange for access to the global economy.

"We say to the Iranians, you are welcome to have access to an unsanctioned economy," Vance explained. "But only if you honor the commitments that you make in this agreement."

The vice president emphasized that the Trump administration believes Iran's nuclear program has already been severely degraded.

"We have affirmatively and comprehensively destroyed their nuclear program," Vance said, adding that Tehran now faces a choice between economic prosperity and pursuing nuclear ambitions it no longer has the capacity to achieve.

Still, significant questions remain.

Vance acknowledged that negotiators must determine exactly how Iran will dispose of its stockpile of highly enriched uranium and what inspection and verification mechanisms will be required before sanctions can be lifted.

He also said details surrounding long-term navigation through the Strait of Hormuz remain under discussion.

"There are a lot of very important details to figure out," Vance said. "A lot of these details are going to be figured out during those 60-day talks."

The administration nonetheless remains optimistic.

Vance noted that direct communication between senior U.S. and Iranian officials has reached levels unseen in decades, creating what he described as a unique opportunity to reshape relations.

For now, the White House is betting that a combination of military strength, economic pressure, and diplomacy can deliver a lasting agreement — one that President Donald Trump argues will bring greater stability to the Middle East while safeguarding American interests.
