Trump Backs Down on Power Plant Strike, Cites Talks — Iran Threatens to Mine the Gulf

DEK: Trump pulls back his 48-hour Hormuz ultimatum after "productive conversations" with Tehran, halting energy strikes for five days; Iran's Defense Council responds by threatening to mine the entire Persian Gulf if its coasts are attacked.

DEVELOPING STORY: The Deadline That Blinked

President Trump halts strikes against Iran’s power plants for five days, citing what he described as “very good and productive conversations regarding a complete and total resolution” of hostilities over the past two days. The climb-down came hours before his self-imposed deadline expired. Trump had threatened Saturday to “obliterate” Iran’s power plants, starting with its largest, if the Strait of Hormuz was not fully reopened within 48 hours.

Iran’s Defense Council responded Monday by warning that any attack on Iran’s coasts or islands would trigger mine-laying across Gulf sea lanes, and that a “decisive and devastating response” would follow any strikes on Iranian energy infrastructure. Iran’s IRGC separately rowed back — but did not fully retract — a threat to target desalination plants that provide drinking water to tens of millions across the Gulf states.

Asian markets plummeted in early Monday trading: Japan’s Nikkei fell 3.5%, South Korea’s Kospi plunged 4.9%, and Hong Kong’s Hang Seng shed 2.7%. Brent crude climbed to approximately $114 a barrel and U.S. crude crossed $100. The International Energy Agency warned the current crisis is worse than the oil shocks of the 1970s, with 11 million barrels per day now effectively removed from global markets.

TRUMP HALTS ENERGY STRIKE THREAT — FIVE-DAY WINDOW OPENS

Trump announced the U.S. and Iran had held productive conversations over the past two days toward a "complete and total resolution" of hostilities, and that he was halting all U.S. strikes on Iran's energy infrastructure for five days. No terms were disclosed. No Iranian confirmation of talks was immediately available. Analysts note Trump said Friday he was "winding down" the war, then Saturday threatened to obliterate power plants, and Monday backed down — calling it a pattern of erratic escalation with no visible endgame.

IRAN STRIKES DIMONA

ISRAEL'S NUCLEAR RESEARCH CENTER HIT FOR FIRST TIME Iranian strikes Saturday hit Arad and Dimona in southern Israel — the site of Israel's main nuclear research center — injuring more than 100 people. It was the first time Iran had targeted the Dimona facility since the war began. Netanyahu visited the damage site and called on other nations to join the war against Iran, saying "it's for the security of the entire world."

IRAN THREATENS TO MINE THE ENTIRE PERSIAN GULF

Iran's Defense Council stated Monday that the only way for "non-belligerent" countries to pass through the Strait of Hormuz is through coordination with Iran, and warned that any attack on Iranian coasts or islands would trigger mine-laying across Gulf sea lanes — a step that would extend the blockade far beyond the strait itself and threaten every Gulf state's maritime access.

IEA: ENERGY CRISIS WORSE THAN 1970s OIL SHOCKS

IEA Executive Director Fatih Birol said the world has lost 11 million barrels per day — "more than two major oil shocks put together" — and called the Hormuz reopening "the single most important solution." Goldman Sachs said Friday that elevated prices could persist through 2027. The IEA said it was consulting governments in Europe, Asia, and North America about releasing additional stockpiles beyond the 400 million barrels already released this

CHINA ENVOY: "THIS WAR SHOULD NEVER HAVE HAPPENED"

China's Middle East envoy Zhai Jun told reporters in Beijing today that the war "should never have happened," adding: "While negotiations were still underway, the United States and Israel suddenly provoked conflict, causing diplomatic efforts to collapse." Zhai called for an immediate halt to all military action and return to negotiations and warned the continued Hormuz closure "would bring unbearable consequences."

What to Watch For

Five-day clock: Trump’s pause on energy strikes runs five days from this morning. Watch whether Iran takes any steps toward reopening Hormuz to non-ally shipping, or whether the talks Trump referenced produce any public framework. The absence of Iranian confirmation of “productive conversations” is notable.

Dimona fallout: Israel’s nuclear research facility being struck for the first time is a significant threshold. Watch whether Netanyahu makes good on his call for allies to join the war, and what the U.S. response to the Dimona strike is diplomatically.

Mine threat: Iran’s Gulf-wide mine threat is the most escalatory statement of the war to date. Watch whether any mine-laying activity is reported or detected by U.S. naval assets.

Murkowski/war powers: The first sitting Republican senator to float a war authorization vote. Watch whether any colleagues join or distance themselves.

Quote of the Day

"While negotiations were still underway, the United States and Israel suddenly provoked conflict, causing diplomatic efforts to collapse. This has left all those who pursue peace deeply regretful and disappointed." — China envoy Zhai Jun, Beijing, March 23, 2026

Bottom Line

Trump blinked on his own deadline — but framed it as diplomacy, not retreat. Iran didn't open the strait, didn't confirm talks, and simultaneously threatened to mine the entire Persian Gulf if its territory is touched. The five-day window is either the beginning of an off-ramp or a pause before the most dangerous escalation of the war. Nobody has said what a deal actually looks like. Oil crossed $100. The IEA says the world is in uncharted territory. And Iran just hit Israel's nuclear research site for the first time.
