Hours before President Donald Trump’s ultimatum regarding the reopening of the Strait of Hormuz, Iran’s ambassador to the United Nations criticized his statements, labeling one of his Truth Social posts as “irresponsible” and “alarming.”

Trump set a deadline for the Iranian government to ensure the Strait of Hormuz, a crucial maritime channel, is reopened by 8 p.m. ET, threatening military action against the nation’s infrastructure if not complied with.

In a Tuesday morning post, Trump warned, “A whole civilization will die tonight, never to be brought back again,” adding, “I don’t want that to happen, but it probably will.”

Speaking at the U.N. headquarters in New York, Amir-Saeid Iravani, the Iranian U.N. ambassador, criticized the President’s remarks, highlighting the unsettling nature of the statement about an entire civilization potentially facing destruction.

Iravani expressed deep concern over Trump’s threats, noting the audacity of declaring intentions to target civilian infrastructure such as bridges and power facilities, and condemned these threats as potential crimes against humanity.

The White House, when asked by Fox News Digital for reaction, said, “The Iranian regime has committed egregious human rights abuses against its own citizens for 47 years, just murdered tens of thousands of protestors in January, and has indiscriminately targeted civilians across the region in order to cause as much death as possible throughout this conflict.”

“As President Trump said today, Iran can never have a nuclear weapon, and the Iranian people welcome the sound of bombs because it means their oppressors are losing. The President will always stand with innocent civilians while annihilating the terrorists responsible for threatening our country and the entire world with a nuclear weapon,” White House deputy press secretary Anna Kelly added. “Greater destruction can be avoided if the regime understands the seriousness of this moment and makes a deal with the United States.”

Trump also said Tuesday, “now that we have Complete and Total Regime Change, where different, smarter, and less radicalized minds prevail, maybe something revolutionarily wonderful can happen, WHO KNOWS?” 

“We will find out tonight, one of the most important moments in the long and complex history of the World,” the president added. “47 years of extortion, corruption, and death, will finally end. God Bless the Great People of Iran!”
