U.S. Ambassador to the United Nations Mike Waltz indicated on Sunday that President Donald Trump intends for a preliminary peace deal framework with Iran to be signed that day, despite ongoing complexities in negotiations.

Waltz, speaking on ABC News' "This Week," acknowledged the challenges presented by Iran's negotiating tactics and internal divisions but reiterated the administration's commitment to finalizing the agreement. The potential deal, as signaled by U.S. officials, aims to reopen the Strait of Hormuz and address Iran's nuclear program over a 60-day period.

While President Trump announced a signing was scheduled for Sunday, Iran has not confirmed this specific timeline. A spokesperson for Iran's foreign ministry stated Saturday that a memorandum of understanding was highly likely to be finalized in the coming days. Details of the agreement remain partially undisclosed, but a senior administration official on Friday outlined key provisions.

The proposed agreement reportedly includes the reopening of the Strait of Hormuz, the dismantling of Iran's nuclear program, and the U.S. acquiring Iran's highly enriched uranium. Ambassador Waltz emphasized the necessity of Iran relinquishing its enrichment capabilities and ending support for terrorist proxies, stating that Iran has agreed to these points.

However, Waltz clarified that the agreement is currently a memorandum of understanding, with many details to be worked out in subsequent negotiations. He also drew distinctions between this potential deal and the 2015 Joint Comprehensive Plan of Action (JCPOA), often referred to as the Obama-era Iran nuclear deal.

A key difference highlighted by Waltz is the principle of "pay for performance" for any unfrozen assets or sanctions relief, meaning there will be no upfront cash payments. This contrasts with the previous deal, where sanctions relief was provided before certain nuclear commitments were fully met.

Waltz also stressed the importance of verification in the new agreement, pointing to what he described as "huge gaps" in the JCPOA's verification mechanisms. He noted that the previous deal allowed for delays, selective acceptance of inspectors, and the classification of potential military sites as off-limits, which hindered comprehensive oversight.

The administration's focus on stringent verification and immediate action on nuclear capabilities suggests a different approach compared to the 2015 agreement, aiming to prevent past issues related to Iranian compliance and inspections.
