Trump's warnings escalate ahead of Iran deadline
Trump sharply escalated tensions with Iran over the weekend, issuing a series of increasingly severe warnings tied to a self-imposed deadline for reopening the Strait of Hormuz .
In a Truth Social post on April 5, he threatened direct strikes on Iranian infrastructure, writing, "Tuesday will be Power Plant Day, and Bridge Day… Open the … Strait… or you'll be living in Hell."
The warning marked a clear shift toward targeting critical infrastructure, including energy and transport systems, if Tehran failed to comply.
On Monday, Trump doubled down publicly, stating that "the entire country can be taken out in one night," signalling the possibility of a rapid, large-scale military response.
By April 7, the rhetoric intensified further. In another post , Trump warned that "a whole civilization will die tonight," framing the moment as a decisive turning point while maintaining pressure on Iran ahead of the deadline.
The escalating language comes as diplomatic efforts to reopen the Strait of Hormuz - a key global oil artery - have failed to produce a breakthrough.

Lawmakers push back, raise 25th Amendment calls
The remarks triggered an immediate backlash in Washington, where lawmakers began openly discussing whether Trump should be removed from office.
Several Democratic lawmakers called for invoking the 25th Amendment, arguing that the president's actions posed a risk to both national and global stability.
Among them, Ilhan Omar wrote on April 6:
"This is not ok. Invoke the 25th amendment. Impeach. Remove. This unhinged lunatic must be removed from office."
Yassamin Ansari also urged action, stating that the amendment "exists for a reason" as the situation risks spiralling further.
Ro Khanna joined a broader group of lawmakers raising similar concerns, while others renewed calls for impeachment.
Outside the Democratic caucus, even some Republicans signalled alarm. Former congresswoman Marjorie Taylor Greene posted :
"25TH AMENDMENT!!! … We cannot kill an entire civilization. This is evil and madness."
The 25th Amendment allows the vice president and a majority of the Cabinet to declare a president unfit to carry out duties, though it requires significant political support to be enacted.
