US President Donald Trump said he has not yet decided whether to resume strikes against Iran, leaving open the possibility of further military action if the ceasefire is breached.

Asked by reporters about a potential violation of the truce, Trump said such a step may become necessary, but no final decision has been made. He also said Tehran is interested in reaching an agreement, while noting that only a small circle of people knows the real state of the negotiations.

In an interview with Newsmax, Trump said Washington had already defeated Iran, though he suggested he would have preferred that victory to look more decisive. According to him, US forces inflicted serious damage on Iran’s navy and air force, its radar infrastructure and the country’s leadership.

Trump also ruled out approving any arrangement under which the United States would provide Iran with enriched uranium for medical or energy purposes. His comments followed remarks by his special envoy, Steve Witkoff, who said such an option had been discussed in negotiations with Tehran.

Against that backdrop, NBC News reported that Iran has stepped up efforts in recent days to restore its missile stockpiles. According to the network’s sources, Iranian forces are using the ceasefire to retrieve missiles and other munitions from underground storage sites, including facilities whose entrances were damaged or blocked after recent US airstrikes.

NBC News sources linked the activity to the growing risk of renewed fighting as negotiations remain stalled.

Pentagon chief Pete Hegseth, speaking before the Senate Armed Services Committee, said the legally established 60-day window during which a US president may conduct military operations without congressional approval has not yet expired. He said the ceasefire pauses or stops the countdown of that period.
