President Donald Trump said the memorandum of understanding with Iran is over and further talks with Tehran are a waste of time.

This declaration signals a sharp escalation in tensions between Washington and Tehran, effectively ending a diplomatic ceasefire framework during a high-profile international gathering.

Speaking Wednesday at the NATO summit in Ankara, Turkey, Trump said the agreement between Washington and Tehran is over [1]. He said the ceasefire is over and labeled the country's leaders as "sick" and "violent" [2, 3].

The president cited recent Iranian attacks on shipping in the Strait of Hormuz and a subsequent exchange of fire as the reasons for the collapse [4, 5]. He said these actions made the memorandum of understanding ineffective, leading him to conclude that any continued diplomatic engagement is futile [4, 5].

These developments follow claims from Iran that its forces targeted 85 U.S. military installations [6]. The scale of these reported strikes has contributed to the breakdown of the previous understanding between the two nations.

Trump's remarks at the summit suggest a shift toward a more confrontational posture. He said that dealing with Tehran is a "waste of time" [1, 2].

While some reports suggest peace talks could technically continue despite being viewed as unproductive, the president's public statements indicate a definitive end to the current framework [7, 1].

"The agreement between Washington and Tehran is over, and further talks are a waste of time."

The collapse of the memorandum of understanding removes a critical diplomatic buffer between the U.S. and Iran. By declaring the ceasefire over in the context of the NATO summit, the U.S. is signaling to its allies and adversaries that it no longer views diplomacy as a viable path to stability in the Strait of Hormuz, potentially increasing the risk of direct military conflict.
