U.N. Ambassador Waltz says administration is confident an Iran peace deal will be signed Sunday

The Trump administration’s U.S. Ambassador to the United Nations Mike Waltz said the administration is “confident” that a final peace deal with Iran will be signed on Sunday, during an appearance on ABC’s This Week.

Waltz told reporter Martha Raddatz that he and his team are “confident,” adding, “Again, I’ll let the final details be announced by them,” referring to the administration’s negotiators and decision-makers rather than publishing the terms in the interview.

The remarks position Sunday as the expected signing date for the final agreement, but Waltz did not provide specific provisions, implementation dates, or enforcement mechanisms during the program. The administration also did not state, in the interview as reported, what legal or procedural steps would follow immediately after signing.

The administration’s approach described by Waltz leaves the public record largely focused on timing and confidence rather than the substance of the agreement. As with many late-stage diplomatic outcomes, details are expected to be released by the administration after the signing, rather than being fully described in advance in public remarks.

The practical impact of a signed Iran deal would typically include questions around how any commitments would be monitored and enforced, what benefits would be conditioned on Iranian compliance, and what executive-branch actions would be required to implement the agreement. Waltz’s comments, however, did not address which agencies would carry out implementation or how oversight would be structured.

The announcement also raises questions about how the U.S. side intends to handle any next steps involving Congress or other institutional roles if legislation or ongoing reporting is required, though no such steps were described in the interview report.

For now, the administration has tied its public position to a specific timing window, with Waltz emphasizing confidence and deferring the negotiated details until they are formally announced.
