US President Donald Trump has threatened to take out Iran in one night if it fails to make a deal before the deadline he set for Tehran to reopen the Strait of Hormuz, a critical global energy route.

Trump's deadline for an acceptable deal - one that includes the free flow of energy through the Gulf - is set for 20:00 EDT (01:00 GMT) on Tuesday.

Speaking at the White House on Monday, Trump stated his belief that reasonable leaders in Iran were negotiating in good faith, but acknowledged the uncertain outcome of these discussions.

Iran has so far rejected proposals for a ceasefire, instead calling for an immediate end to hostilities, post-conflict reconstruction, and the lifting of sanctions.

Trump's news conference was held alongside General Dan Caine, chairman of the Joint Chiefs of Staff, and defense secretary Pete Hegseth, following a successful recovery of crew members from a downed F-15 fighter jet in southern Iran.

Emphasizing the successes of the recent rescue operation, Trump reiterated that military actions could be aimed at Iran’s energy and transportation infrastructure if the Strait of Hormuz is not reopened by the deadline.

The entire country can be taken out in one night – and that night might be tomorrow night, he remarked ominously.

Post-deadline, he warned, Iran would face severe and destructive consequences that could return the nation to a primitive state, with no bridges or power plants.

Despite Iran's prior rejections, Trump maintained hope for a productive negotiation, citing the recent pressure on Iranian leadership due to previous strikes.

Negotiations are complicated by the current communications blackout and delays in relaying messages to Iranian officials, as indicated by sources familiar with the discussions.

Legal experts have raised concerns that the planned military actions, particularly those targeting civilian infrastructure, could amount to war crimes.

Throughout the address, Trump criticized allies like the UK and NATO for their lack of support during the conflict, stating, That's a mark on NATO that will never disappear, and emphasizing that the US does not need the UK.

As tensions continue to escalate, the international community watches closely, with significant military actions already reported across Iran since the war commenced.
