Historic Statement by the Supreme National Security Council: Official End of War Between Iran and the United States

Dimensions of the Supreme National Security Council Statement

The Secretariat of Iran's Supreme National Security Council, in a statement released early this morning, June 15, 2026, officially announced that after months of intensive and difficult negotiations, a Memorandum of Understanding (MoU) to end the state of war between the Islamic Republic of Iran and the United States has been finalized [1]. According to this statement, all military operations on all fronts, including the Lebanese borders, will cease immediately and permanently starting tonight. It was also emphasized that the naval blockade against Iranian ports will end immediately and completely [1][4].

The statement notes that this agreement was achieved in light of the guidance of the Supreme Leader and relying on the steadfastness of the people and the sacrifices of the armed forces. The Supreme National Security Council specified that the official signing of this memorandum will take place on Friday, June 19, in Switzerland [1][3].

The Role of Mediators and Details of the Islamabad Agreement

Reports indicate that this diplomatic breakthrough is the result of continuous mediation by the governments of Pakistan and Qatar. The final negotiations, known as the "Islamabad Negotiations," reached a conclusion on the evening of June 14 [1]. Shehbaz Sharif, the Prime Minister of Pakistan, described the agreement as the "sunrise of peace after the darkness of war" and praised the commitment of both sides to finding a diplomatic solution [2].

U.S. President Donald Trump also confirmed the finalization of this agreement in a message on his social network and, with the phrase "Let the oil flow," ordered the lifting of the naval blockade of Iranian ports in the Strait of Hormuz [2][3]. This agreement includes the full reopening of international shipping routes that had been blocked in recent months due to the conflicts.

Global Reactions and Impact on Energy Markets

Immediately after the news of the agreement was released, global oil prices faced a sharp decline, with Brent crude experiencing a drop of more than 4 percent [3]. Leaders of European countries (United Kingdom, France, Germany, and Italy) welcomed the agreement in a joint statement, calling it an opportunity to restore stability to the global economy [2].

United Nations Secretary-General Antonio Guterres called the agreement a vital step toward ending the conflicts that had engulfed the region since February 2026 [4]. However, reports indicate dissatisfaction and anger among Israeli officials regarding the agreement, with some Hebrew-language media describing Washington's move as ignoring Tel Aviv's security considerations [1].

Remaining Challenges and Future Steps

Despite reaching this understanding to end the war, Iran's nuclear file remains an unresolved issue. According to statements by Kazem Gharibabadi, Iran's Deputy Foreign Minister, negotiations to reach a final and comprehensive agreement that includes the lifting of sanctions have been postponed to a 60-day period following the implementation of the other side's initial commitments [2][3].

International observers believe that while ending military conflicts is a great achievement, the sustainability of this peace will depend on the success of technical negotiations in the coming weeks and how tensions between Iran and Israel are managed [4].
