U.S. Defense Secretary Pete Hegseth said the ceasefire with Iran remains in effect despite an exchange of fire in the Strait of Hormuz [1].

The statement comes as the U.S. attempts to balance a fragile peace with an active military operation to ensure the flow of global commerce. Any escalation in this region could disrupt critical oil shipping lanes and trigger a broader conflict.

An exchange of fire occurred on Monday, May 4 [2]. Reports indicate that several small Iranian vessels were sunk during the encounter [3]. While some accounts state Iranian vessels fired on U.S. ships guiding commercial traffic, other reports focus on the U.S. effort to open the waterway [3, 4].

During a press briefing on Tuesday morning, Hegseth said, "The ceasefire is not over" [1]. He said that the military's current actions are part of a separate mission to secure safe passage for commercial vessels through the strait [1, 3].

"We are securing safe passage for vessels, a separate and distinct project from our war with Iran," Hegseth said [3].

This escort operation is designed to reopen the strait to international trade. On Tuesday, U.S. forces guided the first two commercial ships through the waterway [5]. Hegseth said the operation was a success that challenged Iranian control of the area.

"Iran is embarrassed that we have secured a path through the Strait of Hormuz," Hegseth said [4].

The Pentagon continues to maintain that the escort mission does not constitute a breach of the existing ceasefire agreement, despite the kinetic engagement that took place on Monday [1, 3].

"The ceasefire is not over."

The U.S. is attempting to decouple its strategic objective of keeping the Strait of Hormuz open from the formal diplomatic status of the ceasefire. By defining the escort operation as a 'separate project,' the Pentagon is creating a narrow legal and military corridor to operate in without officially resuming hostilities. However, the sinking of Iranian vessels suggests that the threshold for what Iran considers a violation of the ceasefire may differ from the U.S. interpretation, increasing the risk of accidental escalation.
