President Donald Trump announced that the ceasefire and Memorandum of Understanding with Iran have ended after fresh U.S. military actions.
The collapse of this interim agreement removes a primary diplomatic buffer between two nuclear-armed adversaries, increasing the risk of a wider regional conflict.
Speaking ahead of a NATO summit on Wednesday, June 26, Trump said the diplomatic efforts had failed. The announcement followed a series of U.S. strikes that hit more than 80 Iranian military targets [4]. Trump said that the U.S. had struck "very dangerous people" in Iran [1].
"The ceasefire and MoU are over. I don't want to deal with the Iranians anymore," Trump said [1].
The military escalation has already triggered volatility in global energy markets. Oil prices jumped five percent [1] following the news of the strikes and the termination of the agreement.
Trump said he lacked confidence in the previous diplomatic framework, stating that the ceasefire and interim agreement are now over [3]. While some reports indicated that U.S. negotiators could continue talking with Iranians if they wished [2], other accounts suggested the president viewed such talks as a waste of time [4].
"The ceasefire is over. US negotiators can keep talking with the Iranians if they want," Trump said [2].
This shift in policy comes as the U.S. increases its military posture in the region. The strikes targeted a wide array of military infrastructure, marking a significant escalation in the direct confrontation between Washington and Tehran.
“"The ceasefire and MoU are over. I don't want to deal with the Iranians anymore."”
The termination of the Memorandum of Understanding signals a pivot from a policy of managed tension to one of active military pressure. By explicitly stating a lack of desire to negotiate, the U.S. administration is removing the diplomatic off-ramps that typically prevent localized strikes from escalating into full-scale war. The immediate impact on oil prices reflects market anxiety over the stability of the Strait of Hormuz and global energy supplies.
