President Donald Trump said he is not satisfied with Iran's latest proposal to end the war and declared the ceasefire has terminated.

The decision places the U.S. on a collision course with Tehran and raises the possibility of renewed military engagement without a clear mandate from the U.S. Congress.

Trump sent a letter to congressional leaders on Friday stating that hostilities have terminated [1]. The move comes as the administration faces a war-powers deadline of 60 days [2].

"I am not satisfied with Iran's latest proposal," Trump said [3]. He indicated that the current offer from Tehran does not meet core U.S. demands, specifically the requirement that Iran must never obtain nuclear weapons [4].

Trump said he intends to keep pressure on Tehran to secure a more favorable agreement. The White House said that the conflict could continue even without formal congressional approval [5].

This escalation follows a period of fragile diplomacy where both nations attempted to negotiate a permanent end to the conflict. The termination of the ceasefire marks a significant shift in the administration's approach toward the region [6].

Iran has previously warned of painful retaliation if hostilities resume [7]. The U.S. administration continues to maintain that maximum pressure is the only viable path to a sustainable peace agreement [4].

“"The ceasefire has terminated."”

By declaring the ceasefire terminated and citing the 60-day war-powers deadline, the Trump administration is leveraging a narrow legal window to maintain military pressure. The refusal to accept the proposal over nuclear weapons guarantees that the U.S. will prioritize non-proliferation over an immediate peace treaty, increasing the risk of direct military confrontation in the short term.
