President Donald Trump announced Wednesday that the interim memorandum of understanding and ceasefire with Iran has ended [1, 3].

The collapse of the agreement signals a sharp escalation in hostilities between the two nations, threatening regional stability and global energy markets. Following the announcement, oil prices rose five percent [1].

Trump made the remarks during the NATO summit in Turkey [2, 3]. He described the diplomatic effort as a waste of time and said that the interim memorandum of understanding is over [1, 3].

"The ceasefire is over. It's a waste of time dealing with them," Trump said [1].

The announcement follows U.S. military strikes on Iranian assets. Reports on the catalyst for these strikes vary; some sources said they were retaliation for Iranian attacks on commercial ships in the Strait of Hormuz [1], while others said the strikes followed Iranian attacks on U.S. bases in Kuwait and Bahrain [3].

Trump warned that the U.S. would continue its military campaign immediately. "We're going to hit them hard again tonight," Trump said [2].

The sudden termination of the ceasefire comes as NATO allies gather in Turkey to discuss security coordination. The U.S. position indicates a shift away from the interim diplomatic framework in favor of direct military action to address Iranian aggression in the Gulf region [1, 2].

"The ceasefire is over. It's a waste of time dealing with them."

The formal termination of the interim memorandum of understanding removes the primary diplomatic guardrail preventing full-scale war between the U.S. and Iran. By announcing the collapse of the deal at a NATO summit, the U.S. is signaling to its allies that it is prioritizing military deterrence over negotiation. The immediate impact on oil prices suggests that markets anticipate prolonged volatility in the Strait of Hormuz, a critical chokepoint for global energy supplies.
