The standoff between the United States and Iran has reached a critical tipping point, with just hours left before President Donald Trump’s deadline for reopening the Strait of Hormuz. Trump on Monday (April 6, 2026) said a temporary cease-fire proposal being circulated was insufficient.
Following a failed attempt a possible ceasefire and finally an end to the hostilities, destruction and continues strikes, the US President on Tuesday (April 7, 2026) issued another stark warning on Truth Social, saying, “The whole civilisation will die tonight.” Added that while he does not want such an outcome, Trump stated, “it probably will.”
The deadline, set for 8pm Washington time (00:00 GMT), comes after weeks of escalating conflict, failed diplomacy, and intensifying US-Israeli strikes on Iran.
US-Iran war: How has Iran responded to Trump’s warning?
While Trump has been making some serious threats for the past few days, Iran doesn’t seem to be in the mood of backing out. Tehran, instead, is itself resorting to issuing strong and defiant responses, signalling it is unwilling to back down under pressure. Reacting to Trump’s latest remarks, Iran said, “You and your allies will suffer an unforgettable hit from the ancient civilisation of Iran.”
The Iranian Embassy in Türkiye reinforced this stance, stating, “Alexander burned it. The Mongols ravaged it. History tested it. Iran is still here. A psychopath’s threats won’t end what time couldn’t.”
In a major escalation, Iran is also reported to have cancelled all diplomatic and indirect communication channels with the US, ended message exchanges amid rising tensions, and has also refused to reopen the Strait of Hormuz in exchange for what it called “empty promises”
Did a ceasefire or peace plan come close to success?
Efforts to de-escalate appear to have fallen short at the last moment. Iran on Monday proposed a 10-point peace plan aimed at ending the war, even as US and Israeli strikes intensified. However, Trump dismissed the proposal as insufficient, saying “They made a … significant proposal. Not good enough, but they have made a very significant step. We will see what happens.”
Iran, on its part, has made it clear that a temporary ceasefire is not acceptable, insisting instead on a complete end to the war.
What are the US threats if no deal is reached?
Trump has issued some of the most severe warnings of the conflict so far, openly threatening Iran’s civilian infrastructure. He said, “If they don’t make a deal, they will have no bridges and no power plants.”
In an earlier post, he had stated, “Tuesday will be Power Plant Day, and Bridge Day, all wrapped up in one, in Iran. There will be nothing like it!!! Open the F**** Strait, you crazy bastards, or you’ll be living in Hell – JUST WATCH! Praise be to Allah.”** Further, the US President also warned that US forces would destroy “every bridge in Iran” and cripple “every power plant”.
What is happening on the ground in Iran?
Even before the deadline, intense airstrikes continue across Iran, with Tehran confirming that its key oil export terminal on Kharg Island is under attack. The conflict, which began on February 28, has already triggered a major global energy crisis due to Hormuz disruptions, led to sustained bombing campaigns, and the pushed the region toward a wider war.
Despite the escalating rhetoric, Trump has left a narrow window open for diplomacy. In his post, he said, “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.”
However, with Iran hardening its stance and cutting off communication, the prospects of a breakthrough remain uncertain.
