President Donald Trump announced Wednesday that the cease-fire agreement between the U.S. and Iran has ended [1].

The collapse of the Memorandum of Understanding removes the primary diplomatic barrier preventing a full-scale military escalation in one of the world's most volatile maritime corridors. With the interim agreement void, the risk of direct conflict between the two nations has increased significantly.

Trump made the announcement during a press briefing on the sidelines of the NATO summit in Ankara, Turkey [2]. He said the decision followed recent Iranian strikes on oil tankers in the Strait of Hormuz, which he said made further negotiations a waste of time [3].

"They can talk, but I think they’re wasting their time," Trump said [4].

The president used harsh language to describe the Iranian leadership during the briefing. "They are scum," Trump said [5].

Trump also warned that the U.S. would resume offensive operations immediately. "We’re going to hit them hard again tonight," Trump said [6].

The announcement triggered immediate volatility in global energy markets. Oil prices rose five percent [7] following the statement as traders reacted to the prospect of renewed instability in the Strait of Hormuz.

The U.S. position suggests that the interim agreement was contingent on Iranian restraint in the Gulf. By declaring the cease-fire over on July 8, 2026 [8], the administration is signaling a return to a policy of maximum pressure, and kinetic response to maritime interference.

"They can talk, but I think they’re wasting their time."

The termination of the Memorandum of Understanding marks a shift from tentative diplomacy back to active military confrontation. Because the Strait of Hormuz is a critical chokepoint for global oil supplies, the U.S. decision to resume strikes likely intends to deter further Iranian interference with commercial shipping, though it risks a broader regional war.
