Trump says result of Hormuz ultimatum will be 'very good,' predicts 'total decimation of Iran'

US president also criticizes NATO allies for 'not doing anything' as Iran vows to strike US and Israeli infrastructure in retaliation

US President Donald Trump said Sunday that the result of an ultimatum he issued to Iran to fully reopen the Strait of Hormuz will be "very good," predicting that it would lead to Iran’s "total decimation " if Tehran did not comply.

"You’re gonna find out soon. It’s gonna be very good," Trump told Israel’s Channel 13.

He warned Saturday that if Iran does not reopen the waterway within 48 hours, the US will "hit and obliterate" Iranian power plants, starting with the largest facilities first.

He also criticized NATO allies for their refusal to assist in reopening the strait, saying they were "not doing anything," labeling them “cowards" and "paper tigers.”

NATO Secretary General Mark Rutte requested "understanding" from Trump regarding allied countries' reluctance to support reopening the passage.

Iran responded Sunday to Trump’s ultimatum by warning that it would strike all US and Israeli energy, information technology and desalination infrastructure across the region if its own facilities came under attack.

Iranian Foreign Minister Abbas Araghchi pushed back on claims that Iran had closed the strait, saying ships were hesitating because insurers fear the "war of choice" that the US and Israel initiated — not because Tehran had shut the waterway.

The Strait of Hormuz has been effectively disrupted since early March. Around 20 million barrels of oil normally pass through it daily, and its disruption has driven up shipping costs and pushed global oil prices higher.

US-Israeli strikes against Iran began on Feb. 28 and have reportedly killed at least 1,300 people, including then-Supreme Leader Ayatollah Ali Khamenei.
