The national security adviser indicated that the president holds authority to assess whether Iran breached the ceasefire agreement. Mike Waltz, the U.S. ambassador to the United Nations, stated on Sunday that President Donald Trump is allowing diplomatic efforts with Iran to proceed before resuming military strikes, despite ongoing exchanges of fire following Trump's ceasefire announcement.

Trump stated the ceasefire with Iran remained intact following exchanges of fire over the Strait of Hormuz, characterizing the strikes to ABC News as minimal while Iran contended the agreement had been breached. Waltz indicated on Sunday that Trump would persist with diplomatic efforts following extended negotiations that yielded no resolution, and when mediators such as Pakistan requested additional time for talks rather than resuming military action against Iran, the decision to prioritize negotiation represented an appropriate presidential choice, with diplomacy being exhausted before any return to conflict.

William McRaven, who led Special Operations Command during the operation that resulted in Osama Bin Laden's death 15 years earlier, followed Waltz on the program and indicated the ceasefire had not been upheld, telling the host he understood the ambassador's perspective.

The proposal submitted to Iran outlines a phased approach in which both nations would gradually adjust their military postures over 30 days, with Iran reopening the strait and the U.S. reducing its naval presence, though officials noted that active hostilities would be incompatible with maintaining any truce arrangement. The brief document currently omits references to Tehran's nuclear activities, though both sides are anticipated to discuss management of enriched uranium stockpiles during negotiations.

Officials in the administration have stated on numerous occasions that a primary goal of the conflict is to stop Iran from developing uranium enrichment capabilities that could be used for nuclear weapons. The government continues to assert that its nuclear program does not include weapons development.

On Sunday, reports indicated that Tehran transmitted its reply to a U.S.-drafted proposal regarding a potential resolution to the conflict via intermediaries from Pakistan, though specifics were not disclosed. On Sunday, it was noted that a 30-day timeframe appeared insufficient for reaching a substantial nuclear agreement, given that the JCPOA negotiations required over two years.

McRaven noted that negotiating a complex nuclear agreement with Iran within a 30-day timeframe would be insufficient, referencing the 2015 Joint Comprehensive Plan of Action developed during the Obama presidency. Raddatz additionally inquired about the prior warning issued to Iran by Trump, which stated that the Strait of Hormuz needed to be reopened within 48 hours or face potential strikes on key energy infrastructure.

The threat did not materialise, the waterway continues to operate normally, and petroleum costs have increased noticeably over the past several weeks. Waltz justified the proposed timeframe by noting Iran's history of impeding passage through the strait, and stated he is advocating for a United Nations resolution to bar nations from obstructing maritime traffic in international waters, adding that addressing a decades-long problem in 50 days represents reasonable progress given Iran's repeated threats and past actions in this area. Other nations lack the authority or capacity to engage in similar conduct within these shared maritime routes.
