President Donald Trump issued a blunt ultimatum to Tehran on Sunday, warning that Iran must move quickly toward a deal or face consequences far worse than anything it has seen so far. The message, delivered across multiple platforms and in direct conversations with allied leaders, came as the administration convened its most senior national security officials to weigh both diplomatic and military paths forward.

"For Iran, the Clock is Ticking, and they better get moving, FAST, or there won't be anything left of them," Trump wrote on Truth Social. "TIME IS OF THE ESSENCE!"

The posts were not idle bluster. They arrived alongside a rapid sequence of events, a Saturday war council at Trump's Virginia golf club, a Sunday phone call with Israeli Prime Minister Benjamin Netanyahu lasting more than 30 minutes, and reports from multiple outlets that the White House is preparing for a possible resumption of military operations if Iran continues to stall.

A deal on the table, and an Iranian regime slow to take it

The backdrop is more than five weeks of intermittent peace talks following an April 8 ceasefire, as the Washington Examiner reported. No lasting agreement has materialized. Trump described Iran's latest formal response as "garbage" and "totally unacceptable," and said last week that the ceasefire itself was on "massive life support."

Speaking aboard Air Force One on Friday while returning from Beijing, Trump made clear he had little patience for diplomatic theater.

"Well, I looked at it, and if I don't like the first sentence, I just throw it away. It's got to be a real 20 years, not a fake 20."

That reference to a 20-year moratorium on Iran's nuclear program marks a notable shift. Trump had previously demanded that Tehran permanently abandon its nuclear ambitions. The willingness to discuss a two-decade suspension suggests the administration is offering Iran a genuine off-ramp, one the regime has so far refused to take seriously.

Trump also revealed that Iranian negotiators had indicated they would allow the United States to retrieve Tehran's highly enriched uranium stockpile, then quietly dropped the concession from their formal written response. "They did two days ago," Trump said when asked whether Iran had agreed to relinquish the material. "But they changed their mind because they didn't put it in the paper."

That kind of bait-and-switch is familiar to anyone who has watched Iran's negotiating behavior over the past two decades. It is exactly the pattern that previous U.S. diplomatic pivots toward Tehran have struggled to overcome.

The Saturday war council and what comes next

CNN and Axios both reported that Trump met Saturday with Vice President JD Vance, Secretary of State Marco Rubio, CIA Director John Ratcliffe, and envoy Steve Witkoff to discuss Iran and possible next steps. The meeting focused on both diplomatic and military options.

Multiple reports indicated Trump plans to convene another session Tuesday in the White House Situation Room as deliberations continue. The pace of those meetings tells its own story: this is not a president content to let negotiations drift.

In a phone interview with Axios on Sunday, Trump struck a tone that was firm but not closed to resolution. "We want to make a deal," he said. "They are not where we need them to be. They will have to get there or they will be hit badly."

He went further in remarks to Israel's Channel 13, saying flatly that "the Iranians should be afraid of what's going on right now." Fox News reported that regional intelligence officials described Tehran as pursuing a strategy of "deception and delay" while believing Trump could restart military action.

Israel preparing for 'days to weeks of fighting'

The Israeli side of the equation is moving just as fast. Kan, the Israeli public broadcaster, reported that Trump and Netanyahu discussed the possibility of renewed military action during their Sunday call. Ynet, citing an unnamed Israeli official, said the question remains unresolved and Trump has not made a final decision.

That official offered a telling assessment of where things stand: "He needs to be at peace with the decision himself. And if he decides to resume the fighting, Israel will likely be asked to join."

Israel's Channel 12 reported Friday, citing a senior Israeli official, that preparations were already underway for what could amount to "days to weeks of fighting." The same official said bluntly: "The Americans understand that negotiations with Iran are going nowhere."

The New York Times published a Friday report stating the United States and Israel were carrying out intensive preparations for possible renewed operations should diplomacy fail. That reporting, combined with the Saturday and Sunday meetings, suggests the administration is not simply posturing. It is building a decision framework with a clear deadline.

Some allies of the president have urged him not to squander leverage by offering too much at the negotiating table, a concern that appears well-founded given Tehran's pattern of walking back concessions.

Drone strikes rattle the Gulf

The diplomatic standoff played out Sunday against a backdrop of fresh violence in the region. A drone strike triggered a fire outside the Barakah nuclear power plant in the United Arab Emirates after one of three drones entering the country struck an electrical generator outside the facility's inner perimeter. UAE officials called the incident a "dangerous escalation" and an "unacceptable act of aggression."

The International Atomic Energy Agency said radiation levels at the site remained normal. But the symbolism of a strike near a nuclear facility, regardless of who launched it, was impossible to miss.

Separately, Saudi Arabia announced it intercepted and destroyed three drones entering its airspace from Iraq. Riyadh warned it reserved the right to respond "at the appropriate time and place." No group has been publicly identified as responsible for either set of drone operations, but the incidents underscore the fragility of the current regional order.

Trump reinforced his warnings Sunday by posting and reposting a rapid series of Iran-focused graphics and military-themed imagery on Truth Social. One was an uncaptioned image showing a Middle East map overlaid with an American flag and a series of arrows directed toward Iran. Others depicted U.S. naval and drone operations targeting Iranian fast boats, drones, and maritime assets, alongside graphics contrasting his administration's posture toward Tehran with prior administrations.

The visual messaging was not subtle. It was not meant to be. As Just The News noted, Trump's social media campaign signals a narrowing window for Tehran to act.

Iran's defiant response

Tehran, for its part, is not backing down publicly. Brig. Gen. Reza Talaei-Nik, the Iranian Armed Forces spokesman, warned that Iranian forces stood ready to respond forcefully to any renewed military action.

Iran's deputy parliament speaker, Hamidreza Haji Babaei, went further with a threat aimed at the global economy:

"If the enemy attacks our oil, no country in the world will be able to access oil in the region."

Iranian state-linked reporting also described Tehran as seeking formal recognition of Iranian authority over the Strait of Hormuz, a demand that, if serious, would represent a non-starter for the United States and its Gulf allies. Newsmax reported that Iranian state-linked outlets claimed Washington offered no real concessions in the latest diplomatic exchange.

The combination of Iran's maximalist demands, its withdrawal of the uranium concession, and its military bluster paints a picture of a regime that either believes it can outlast American pressure or has not yet grasped how seriously the current administration is treating the timeline.

Trump's willingness to use every available platform to apply pressure, from Truth Social posts to direct calls with allied heads of state, reflects a president who treats public messaging as an extension of negotiating strategy, not a substitute for it.

The week ahead

The Tuesday Situation Room meeting looms as the next inflection point. By then, the administration will have had the benefit of the Saturday review, the Sunday Netanyahu call, and whatever back-channel signals Tehran sends in the interim.

Several questions remain unanswered. What specific deal terms beyond the 20-year moratorium is Trump demanding? What final decision, if any, emerged from the weekend discussions? And who launched the drones that struck near the Barakah plant and entered Saudi airspace?

What is clear is that the administration has moved beyond the phase of open-ended negotiation. The president has publicly set a clock. His national security team is meeting at an accelerated pace. Israel is preparing for the possibility of renewed operations. And Iran's response so far has been to stall, retract concessions, and issue threats about oil.

Trump has made bold foreign-policy declarations before. But this one comes with a visible military planning apparatus behind it and a partner in Jerusalem that appears ready to act.

Iran has been offered a deal. It has been offered time. It has been offered a face-saving path. What it has not been offered is forever, and that, more than any single Truth Social post, is the message Tehran needs to hear.
