President Donald Trump announced Wednesday that the memorandum of understanding with Iran to end hostilities is over.

The collapse of the temporary cease-fire agreement signals a return to direct military confrontation between the two nations, threatening stability in the Gulf region.

Trump said the decision followed Iranian attacks on U.S. military bases in the Gulf and three shipping vessels [1] in the Strait of Hormuz. He said that these actions violated the terms of the agreement. In response to the escalation, Trump called Iranian leaders "scum, liars" [2].

U.S. Central Command had already responded to the aggression on Tuesday, striking more than 80 Iranian targets [3]. Trump said that the military response would continue immediately, stating, "We’ll hit them hard again tonight" [4].

Despite the termination of the memorandum and the promise of renewed strikes, the president said that diplomatic talks could still continue. However, he expressed a personal distaste for the Iranian leadership, saying, "I don’t like them" [5].

The current volatility follows a period of fragile stability under the memorandum. The recent strikes on shipping and military infrastructure represent a significant breach of the previous arrangement, one that the administration is now meeting with an expanded kinetic response.

"We’ll hit them hard again tonight."

The termination of the MOU removes the primary diplomatic guardrail preventing full-scale conflict in the Persian Gulf. By combining high-volume military strikes with the formal end of a cease-fire, the U.S. is shifting from a strategy of containment to one of active deterrence, which increases the risk of accidental escalation in the strategically vital Strait of Hormuz.
