The United States officially lifted its blockade of Iran on Thursday, allowing oil tankers to resume transit through the Strait of Hormuz as a tentative ceasefire agreement took effect. While shipping activity has begun to normalize, the diplomatic rollout of the deal remains uncertain, with Vice President JD Vance delaying a planned trip to Switzerland for a ceremonial signing. The agreement, signed by President Donald Trump, aims to halt hostilities and initiate a 60-day window for broader negotiations on Iran’s nuclear program.
How is the maritime blockade being resolved?
Commercial shipping has begun to move through the Strait of Hormuz for the first time in 110 days, according to data from Lloyd’s List Intelligence. While the U.S. has eased its military blockade, the waterway is not fully open. Phillip Belcher, marine director of the trade group Intertanko, stated that the central route remains blocked by an estimated 80 mines. Ships are currently utilizing secondary northern and southern routes, though these paths lack the capacity of the central channel. U.S. Central Command noted that American warships will remain in the region to monitor compliance with the ceasefire agreement.
What is the status of the U.S.-Iran negotiations?
The diplomatic timeline faces potential delays following Vice President Vance’s announcement that he may postpone his travel to Switzerland. This trip was intended to host a ceremonial signing and serve as a launchpad for future talks. Similarly, Pakistani Prime Minister Shehbaz Sharif postponed a planned visit to the same region, as officials determined the ceremony was no longer urgent after both sides had already signed the pact. Meanwhile, Iranian Supreme Leader Ayatollah Mojtaba Khamenei publicly endorsed direct negotiations with the U.S. for the first time, signaling a potential shift in Iranian policy despite historical opposition from hardliners.
What are the terms of the nuclear agreement?
Trump envoy Steve Witkoff informed U.S. lawmakers in a private briefing that Iran has agreed to invite the International Atomic Energy Agency (IAEA) to inspect nuclear sites and identify locations of enriched material. According to individuals familiar with the briefing, a side letter drafted between Tehran and the IAEA facilitates this access. The broader deal requires Iran to dilute its stockpile of highly enriched uranium under international supervision and prohibits the development of nuclear weapons. While the U.S. has waived its own sanctions, European Union foreign policy chief Kaja Kallas confirmed that the 27-nation bloc will maintain its existing sanctions on Iran.
What happens next?
The agreement initiates a 60-day period for the U.S. and Iran to negotiate a final resolution regarding Tehran’s nuclear program. Future progress may be influenced by several factors: the speed at which the Strait of Hormuz can be cleared of mines, the success of IAEA inspections, and the ability of the Trump administration to build domestic support for the deal. Despite the ceasefire, President Trump has left the option open to resume military action if necessary. The administration maintains that the accord will force Iran to change its behavior, though critics in Congress have questioned whether the U.S. conceded too much in exchange for the immediate lifting of oil sanctions.
