Three Gulf Leaders Block Trump's Iran Strike — and Buy 72 Hours That Could Reshape the Middle East

The Call That Stopped a War

On Monday, May 18, President Donald Trump announced on Truth Social that he had called off a “scheduled” U.S. military attack on Iran planned for the following day. The reason? A direct plea from three of the most powerful leaders in the Gulf: Saudi Crown Prince Mohammed bin Salman, UAE President Mohamed bin Zayed, and Qatar’s Emir Sheikh Tamim bin Hamad Al Thani.

“I have been asked by the Emir of Qatar, the Crown Prince of Saudi Arabia, and the President of the United Arab Emirates to hold off on our planned Military attack of the Islamic Republic of Iran, which was scheduled for tomorrow,” Trump wrote. He added that “serious negotiations are now taking place” and that a deal would be “very acceptable to the United States of America, as well as all Countries in the Middle East, and beyond.”

The president instructed Secretary of War Pete Hegseth and Chairman of the Joint Chiefs General Daniel Caine to stand down — but kept forces ready for “a full, large scale assault of Iran, on a moment’s notice” if negotiations collapse.

Why the Gulf States Intervened

The intervention wasn’t spontaneous. It came amid a weekend of escalating violence that directly threatened Gulf security:

Saudi Arabia intercepted three drones that entered its territory from Iraqi airspace on Sunday.
A drone strike caused a fire at the UAE’s Barakah Nuclear Power Plant — an unprecedented attack on civilian nuclear infrastructure.
Iran’s missile and drone attacks on Gulf states have been a recurring pattern since the US-Israel war on Iran began on February 28.

For Riyadh, Abu Dhabi, and Doha, the calculus was clear: another round of American strikes on Iran would almost certainly trigger more Iranian retaliation against Gulf territory. The Gulf states have been caught in the crossfire of a war they didn’t start, and their leaders decided that a diplomatic off-ramp — even a temporary one — was worth the political capital of directly challenging Trump’s military timeline.

Speaking to reporters later, Trump said the Gulf leaders asked for “two or three days” because they believe they are “getting close to a deal.” He characterized the delay as possibly “forever” — or “possibly for a little while.”

The Stakes: Strait of Hormuz and Nuclear Red Lines

Two issues dominate the negotiations:

1. The Strait of Hormuz remains effectively closed. Iran shut the critical waterway — through which roughly one-fifth of the world’s oil passes — early in the conflict. The closure has roiled global energy markets and disrupted supply chains dependent on Gulf oil exports. Any deal must address Hormuz’s reopening.

2. Iran’s nuclear program. Trump’s post emphatically stated any deal “will include, importantly, NO NUCLEAR WEAPONS FOR IRAN!” But Iran maintains its enrichment rights under the Non-Proliferation Treaty. Iranian Foreign Ministry spokesperson Esmail Baghaei reiterated Monday that “Iran’s right to enrichment is recognized under the NPT agreement” and that “there is no need for another party to recognize this right for Iran.”

Iran has reportedly relayed an amended set of terms to the Trump administration through Pakistani mediators. Iranian President Masoud Pezeshkian struck a defiant but diplomatic tone, stating: “Dialogue does not mean surrender. The Islamic Republic of Iran enters into dialogue with dignity, authority, and the preservation of the nation’s rights.”

A New Gulf Assertiveness

The episode reveals a significant power shift. Saudi Arabia, which previously refused to allow the U.S. to use its airspace or bases for the shelved “Project Freedom” Hormuz operation, has now gone further — actively lobbying Trump to delay military action. This is the same kingdom that, according to Western officials, carried out its own covert retaliatory strikes on Iranian soil in March.

The Gulf states are no longer passive beneficiaries of American security guarantees. They are active strategic players with their own red lines, and they’ve demonstrated a willingness to leverage their relationships with Washington to shape outcomes.

Meanwhile, the diplomatic chain extends beyond Riyadh. The House of Saud analysis notes a five-day diplomatic sequence from Riyadh to Beijing, where Chinese President Xi Jinping holds significant leverage over any final deal. Pakistan continues to serve as a critical mediator, having already persuaded Trump to extend the original April 7 ceasefire indefinitely.

Iran’s Response

Iran’s military leadership responded to the reprieve with characteristic defiance. Ali Abdollahi Aliabadi, commander of Iran’s Khatam al-Anbiya Central Headquarters, declared: “Iran and its armed forces are more prepared and stronger than ever before. We will cut off the hand of any aggressor.”

The statement serves as a reminder that while the Gulf states may have bought time, the underlying dynamics of the conflict remain unresolved. Iran has not reopened the Strait of Hormuz. Its proxy forces in Iraq continue to launch drones at Saudi Arabia. And neither side has publicly agreed to the other’s core demands.

What Happens Next

The 72-hour window expires around Thursday, May 21. Three scenarios emerge:

A deal is reached. Iran agrees to nuclear concessions and reopens Hormuz; the U.S. lifts sanctions and ends military operations. The Gulf states claim diplomatic victory.
Negotiations stall. Trump resumes military strikes. Iran retaliates against Gulf infrastructure. The war escalates to a new level.
The window extends. The Gulf leaders plead for more time, and Trump — valuing the political capital of having “tried diplomacy” — grants another delay, kicking the can further down the road.

For now, the Middle East holds its breath. Three Gulf monarchs have wagered their credibility on a bet that diplomacy can succeed where military force has failed. Whether that bet pays off will shape the region for years to come.
