The US-Iran ceasefire agreement is under severe strain after US President Donald Trump declared the truce "over" on July 8, 2026, amidst tit-for-tat strikes between the two nations. The US launched retaliatory strikes on Iran following alleged Iranian attacks on commercial vessels in the Strait of Hormuz.

Background to the Ceasefire Agreement

The US and Iran signed a memorandum of understanding (MoU) on June 17, 2026, aimed at paving the way for serious negotiations on outstanding issues, including Iran's nuclear programme and western sanctions. The MoU required Iran to allow safe passage of tankers through the Strait of Hormuz and never to develop a nuclear bomb, while the US agreed to lift its maritime blockade and ease sanctions.

Escalating Tensions in the Strait of Hormuz

The implementation of the MoU has been complicated by two major hurdles: the war in Lebanon and the status of the Strait of Hormuz. Iran has insisted that tankers take its designated route through the strait, while the US and some Gulf countries have encouraged them to take an alternative route along Oman's coast. The US blamed Iran for attacks on three ships passing through the Omani route over the weekend and launched strikes on the country.

In response to the US strikes, Iran targeted multiple US bases and military assets in Bahrain and Kuwait, and claimed to have shot down an American MQ-9 drone. Mohammad-Bagher Ghalibaf, Iran's Parliament Speaker, accused the US of violating the MoU, stating that "the era of bullying and extortion is over... we don't fold."

What's Next for the US-Iran Ceasefire

The current escalation leaves US President Donald Trump with limited options. Continuing military pressure has failed to persuade Iran to restore the status quo in the Strait of Hormuz. Further escalation risks undermining the diplomatic process and leaving Iran's nuclear programme unresolved. The situation remains volatile, with the international community watching closely for the next developments.
