U.S. Vice President JD Vance said Monday that talks in Switzerland established a good foundation for a permanent deal to end the war [1].

The agreement marks a critical step toward stabilizing the region by addressing both the active conflict and the long-standing dispute over nuclear proliferation.

Senior negotiators from the United States and Iran concluded a round of discussions that lasted nearly 18 hours [2]. Following the meetings, Vance said the discussions yielded a lot of good progress [3]. He said the talks set a good foundation for a permanent deal to end the war [1].

As part of the preliminary framework, Iran agreed to let international nuclear inspectors back into the country [4]. This move is intended to verify compliance with nuclear non-proliferation standards, while the two nations work toward a comprehensive settlement.

Both parties have also agreed to a roadmap toward a final deal within 60 days [5]. This timeline establishes a strict window for diplomats to resolve remaining grievances and formalize the cessation of hostilities.

Vance said to the media in Switzerland after the delegations concluded their session on Monday, June 22, 2026 [1]. The talks were specifically intended to solidify a permanent end to the war between the United States and Iran [1].

"These talks set a good foundation for a permanent deal to end the war."

The resumption of international nuclear inspections is a high-stakes concession from Tehran that provides the U.S. with the transparency needed to justify a permanent peace deal. By setting a 60-day deadline, both administrations are attempting to maintain diplomatic momentum to prevent a return to open conflict.
