Why Trump pulled the set off on Iran: MARK HALPERIN reveals the second that sealed Tehran’s destiny… and the final word query that may decide how this ends

This is regime change of a different sort than we have ever seen.

Not the Iraq model, with boots on the ground and schoolhouses built in someone else’s dust. Not the long, grinding Afghan vigil, with American blood and treasure poured into valleys that never really loved America back. 

The United States is not preparing to pave roads in Tehran or construct firehouses in Shiraz. There will be no nation-building seminars, no billions spent trying to midwife a new civic culture in the Iranian countryside.

This is something colder, leaner, and far more Trumpian.

As David Ignatius observed on ‘Morning Joe’ on MSNOW Saturday morning, the president has what he called a ‘Viking’ playbook: massive military action, then withdrawal, leaving the vanquished to sort through the wreckage once the longships have pulled back over the horizon. 

He has offered it rhetorically before, as in Venezuela. But Iran, even weakened and economically brittle, is not Venezuela. Its proxies are bloodthirsty. Its regime is seasoned in survival. Its geography and its grievances and its military are not so easily rearranged.

From the start of this term, Donald Trump resolved he would not spend four years playing whack-a-mole with Tehran — responding episodically to nuclear brinkmanship, missile testing, terror sponsorship. He did not want to manage the problem. He wanted to end it.

Twice on Friday, in unscripted exchanges with the press, he spoke with unmistakable vexation about Iran’s negotiating posture. He sounded less like a dealmaker and more like a man who believed he had been played. 

Even administration officials most inclined toward diplomacy were deeply skeptical that Tehran was doing anything but stalling for time.

The tells were there for those who wished to see them: urgent evacuations of diplomatic personnel from the region; the quiet but unmistakable repositioning of US military assets; the curious silence between Washington and Jerusalem even as forces in both countries moved to high alert. 

Chuck Schumer emerged from a Gang of 8 briefing from the administration with a public reaction that suggested gravity without illumination.

And then there is the cast of characters at the center of this moment. Reputation notwithstanding, the core national security decision-makers — Trump, Rubio, Hegseth, Miller, and yes, even Vance — are swaggering hawks when it comes to regimes they view as evil. 

They harbor open disdain for European allies they see as feckless, unwilling to take the hard steps required to keep the world safe. They are comfortable acting without permission slips, including from Congress, from Europe, from the Gulf States.

The president had publicly pledged support for Iran’s recent popular uprising — a once-in-a-generation crack in the theocratic facade. He did not intend to let it pass unused. 

When Trump faces a war decision, he is both methodical and a riverboat gambler. He studies options exhaustively; and then, if he believes the moment demands it, he jumps into the unknown. The much-discussed ‘pin-prick’ strike — one last warning shot to coax surrender — was judged insufficient. If you are going to swing, swing hard.

Paradoxically, Iran is both deeply dangerous and deeply vulnerable. Its economy is battered. Its population restless. Its security state stretched thin. A massive threat at its most brittle.

And yet, most of us woke up Saturday morning surprised.

No extended case was made to the American people. No drumbeat of speeches by Rubio or Vance laying out the moral and strategic necessity. The Omanis were publicly saying the talks were going well.

Rubio was scheduled to head to Israel next week. Administration officials signaled to reporters that no strike was imminent, that more diplomacy was coming.

Then, with operational security that was stunning even by Trump standards, the strike came — just hours after the president arrived at Mar-a-Lago from what appeared to be a routine domestic trip to Texas. Surprise, once again, was a weapon.

This is regime change, or at least the assumption of responsibility for its possibility, from a president who defined ‘America First’ as skepticism of foreign intervention. It is a remarkable pivot, particularly in a government where JD Vance’s intervention-skeptic instincts carry real weight.

Make no mistake: this is a war of choice. Hawks will protest the phrase, but it is true. And wars of choice carry political peril. Anything short of complete, quick, and unmistakable success risks distracting from — or consuming — the White House’s domestic focus on affordability and the midterms. 

The president detests war, especially the loss of American life. Now he has placed himself in a position where such loss is possible.

The questions now tumble forward like loose stones down a mountainside.

Which Iranian leaders will be killed? Do the people rise? What retaliation can Tehran mount through missiles or proxies? How effective are US and Israeli missile defenses? Without boots on the ground, how many Americans might still die? 

What cyber dimensions are unfolding even now in silence? How many drones are in the sky as part of what is surely the biggest such attack in the history of the world? What special operations are the Israelis and US conducting on the ground?

What happens to world markets, including and especially oil prices over the weekend and on Monday? 

When does Trump next speak, after his overnight video address, how do congressional Democrats respond — the leaders, and then the rank and file? Are there war powers votes next week? How often will the executive brief the legislature? What do the first polls say?

What does Vladimir Putin truly think? Xi Jinping? How does this reshape Ukraine’s fragile path toward peace? When does the United Nations convene, and with what effect?

Who wins — what is sure to be one of the biggest war-time propaganda battles in world history, given the proliferation of digital media?

Where is Marco Rubio for the next seven days? Has Washington quietly cultivated alternatives — the Shah’s son, others — for a best-case scenario? If the regime’s apex collapses, who fills the vacuum?

In the age of instant reaction, even the television anchors will scramble to their studios, racing events that are moving at the speed of hypersonic weapons and encrypted code.

This is not the regime change of 2003. It is not the humanitarian intervention of the 1990s. It is something sharper and more transactional: strike, destabilize, withdraw, and let history’s currents do the rest.

Whether that current carries Iran toward freedom or chaos — and whether it elevates or engulfs the Trump presidency — is a question that will not wait long for its answer.

Joe Scarborough reported on a special weekend edition of his program that he spoke to Trump on Friday around 2pm ET, during which the president waved off the peace talks, saying ‘The next two weeks will be very interesting.’

Trump said he was determined to do what other presidents hadn’t done, and actually take action against Iran.

A few hours later, he did just that.
