President Donald Trump rejected Iran's response to a peace proposal on Monday, and said the terms were "totally unacceptable" [1].

The deadlock threatens the stability of global energy markets and maritime security, as the two nations remain far apart on a framework to end the war and reopen the Strait of Hormuz [1, 2].

Negotiations centered on the reopening of the Strait of Hormuz in the Persian Gulf region [3]. The U.S. and the Islamic Republic of Iran have struggled to find common ground on the specific terms required to end hostilities, and restore commercial transit through the waterway [1].

Trump said the Iranian response did not meet the requirements of his proposal [1]. While the U.S. president stopped short of declaring a formal resumption of fighting, the rejection leaves the conflict in a precarious state [1].

Iran responded to the U.S. stance with warnings of new attacks if the United States continued its current position [2]. This escalation follows a period of intense diplomatic wrangling over the peace framework [1].

Israeli Prime Minister Benjamin Netanyahu said the war is "not over" [1]. The situation remains volatile as the Strait of Hormuz stays effectively blocked, impacting international shipping and oil flows [1, 2].

"Totally unacceptable."

The failure to reach an agreement on the Strait of Hormuz increases the risk of a prolonged maritime blockade in one of the world's most critical oil chokepoints. With the U.S. rejecting the current Iranian terms and Iran threatening further attacks, the diplomatic path to de-escalation is narrowing, potentially prolonging the regional conflict and sustaining pressure on global energy prices.
