Iran has submitted a formal response to a U.S. peace proposal intended to end the current war, according to Iranian state media.

The development marks a critical juncture in the conflict, as both nations seek to resolve disputes over nuclear proliferation and the security of global shipping lanes. A failure to reach an agreement could prolong active hostilities and further destabilize the region.

Islamic Republic News Agency (IRNA) said Sunday that the Iranian government provided the reply to a one-page memorandum [1] issued by the U.S. The communication was transmitted through Pakistani mediators [2].

The proposal arrives after 10 weeks of war [3]. The U.S. aims to secure the reopening of the Strait of Hormuz, and establish guarantees to prevent Iran from developing nuclear weapons [4].

Reports on the content of Iran's response vary. Some sources said the reply offered few details [1]. However, other reports said the response specifically discussed the reopening of the Strait of Hormuz, and a 30-day extension to the cease-fire [5].

These negotiations follow a period of stalled talks between the two governments. The U.S. proposal focuses on a structured path toward a permanent end to the conflict, provided that strategic security concerns in the Persian Gulf are addressed [4].

Officials have not yet confirmed if the current terms are sufficient to trigger a full diplomatic resolution. The use of third-party mediators suggests a continued lack of direct diplomatic channels between Tehran and Washington [2].

The transition from stalled talks to a formal exchange of memoranda indicates a shift toward pragmatic diplomacy. By utilizing Pakistani mediators, both parties are attempting to find a face-saving mechanism to halt a 10-week conflict. The focus on the Strait of Hormuz underscores that the conflict is as much about global energy security and maritime law as it is about regional territorial or nuclear disputes.
