President Donald Trump warned Iran it has three days [1] to agree to a cease-fire or face catastrophic consequences.

The ultimatum increases the risk of direct military conflict between the U.S. and Iran while diplomatic efforts to stabilize the region are currently underway.

Trump made the remarks Sunday, May 12, 2026 [2], while in Pakistan shortly before boarding a flight to China [3]. The president used expletives during the announcement, stating he would ensure Iran is completely decimated if the country does not open the Strait of Hormuz [4].

The threat follows ongoing peace talks in Pakistan aimed at preventing the further escalation of the Iran-Israel-U.S. conflict [5]. Trump said to reporters that if these peace talks fall apart, Iran will be completely decimated [6].

This high-pressure tactic is intended to force Iran to cease hostilities and reopen the critical maritime passage [5]. The president, who is 79 [7], issued the warning as a final demand to avoid further military action.

"Iran has three days to agree to a cease-fire or face catastrophic consequences," Trump said [8].

While some reports suggest the warning was issued in Tehran, other accounts place the president in Pakistan during the encounter [3, 9]. The primary focus of the demand remains the immediate reopening of the Strait of Hormuz, and a cessation of hostilities [4].

"Iran has three days to agree to a cease-fire or face catastrophic consequences."

The use of a strict 72-hour deadline shifts the U.S. strategy from diplomatic negotiation to an explicit ultimatum. By linking the survival of the Iranian state to the outcome of peace talks in Pakistan and the accessibility of the Strait of Hormuz, the administration is leveraging a critical global oil chokepoint to force a geopolitical concession.
