President Donald Trump (R-FL) announced Wednesday during the NATO Summit in Ankara, Turkey, that the ceasefire between the U.S. and Iran has ended.

The collapse of the truce signals a sharp escalation in Middle East tensions, threatening global energy markets and increasing the risk of direct conflict between the two nations.

Speaking at the summit, Trump said negotiations with Tehran were "a waste of time dealing with them." He said the U.S. intends to escalate military operations, stating, "We're going to hit them hard again tonight."

The breakdown of the agreement follows a series of violent encounters. Reports vary on the specific trigger for the collapse; some sources said the ceasefire ended after the U.S. targeted Iran overnight, while others report the truce broke down after Iran launched strikes on three ships [3] in the Strait of Hormuz.

U.S. military actions have already been extensive. The U.S. launched strikes on more than 80 Iranian military targets [2] as part of the policy shift. Trump said these actions were a response to the failure of diplomatic efforts.

The economic impact of the announcement was immediate. Oil prices rose by five percent [1] following the declaration, reflecting market volatility as traders brace for potential disruptions to oil shipping lanes in the Persian Gulf.

"For me, I think it's over. It's just a waste of time dealing with them."

The termination of the ceasefire represents a pivot from diplomatic engagement back to a policy of maximum pressure and direct military kinetic action. By announcing this during a NATO summit, the U.S. is signaling to its allies that it views the Iranian threat as an immediate priority, potentially seeking broader multilateral support for future operations in the region.
