US Pauses 'Project Freedom' Escort Operation in Strait of Hormuz Amid Iran Nuclear Talks
The United States announced a pause to "Project Freedom" — its military operation to escort commercial ships through the Strait of Hormuz — citing significant diplomatic progress toward a comprehensive agreement with Iran.
The pause was announced following a request from Pakistan (serving as a mediator) and several other countries, with the US administration indicating "great progress" had been made toward a "complete and final agreement" with Tehran.
Iran had earlier proposed separating the Hormuz reopening from nuclear negotiations, offering to allow freedom of navigation in exchange for a ceasefire, with nuclear talks to follow in a subsequent phase.
The blockade of the Strait — initiated by Iran after US and Israeli airstrikes in late February 2026 — has removed over 10 million barrels per day from global oil markets.
Iran's closure of the strait involves a combination of mine-laying, seizure of merchant ships, Revolutionary Guard naval patrols, and toll-collection demands on passing vessels.
Strait of Hormuz: Strategic Geography
The Strait of Hormuz is the world's most critical maritime oil chokepoint, connecting the Persian Gulf to the Gulf of Oman and the wider Indian Ocean. It is approximately 90 nautical miles long and narrows to just 21 nautical miles at its tightest point, with two navigable channels — each roughly 2 miles wide — separated by a median line.
The Strait's closure since early March 2026 has triggered the largest supply disruption in oil market history, which is why the US launched a naval escort operation and is now in active diplomatic negotiations with Iran.
Freedom of Navigation and UNCLOS
The right of transit passage through international straits is governed by Part III of the United Nations Convention on the Law of the Sea (UNCLOS), specifically Article 37 and Articles 39–42. Unlike innocent passage, transit passage is non-suspendable — it applies to all vessels (surface, submarine, and aircraft) and cannot be restricted even during armed conflict.
The US justification for Project Freedom and the UNSC resolution rests on freedom of navigation as a non-derogable right. Iran's blockade is framed as a violation of international maritime law, providing legal basis for multilateral intervention.
Iran's Nuclear Programme: Background
Iran's nuclear programme has been at the centre of international diplomacy since the early 2000s. The Joint Comprehensive Plan of Action (JCPOA), commonly called the Iran nuclear deal, was concluded in 2015 between Iran and the P5+1 (US, UK, France, Russia, China, and Germany). It imposed limits on Iran's uranium enrichment in exchange for sanctions relief.
The US pause of Project Freedom is contingent on diplomatic progress that must eventually address both the Strait reopening and Iran's nuclear programme — two entangled but distinct issues that Iran has tried to sequence separately.
Pakistan as Mediator: Regional Diplomatic Role
Pakistan has served as a communication channel between the US and Iran in the 2026 crisis, playing a mediating role consistent with its historical position of maintaining ties with both Western powers and Iran. Pakistan shares a long land border with Iran and has deep religious, trade, and energy ties with Tehran.
Pakistan's request that the US pause Project Freedom formed the immediate diplomatic trigger for the announcement, underscoring South Asia's stake in the Hormuz crisis.
