The delicate peace between the US and Iran has fractured following a series of attacks on 6 July, when Iranian forces targeted three commercial vessels transiting the Strait of Hormuz. In an immediate response, the US bombed over 80 locations within Iran the following day. US President Donald Trump declared the existing peace agreement effectively void, and the situation has since spiraled into a cycle of mutual retaliation. Understanding the rapid breakdown of this deal requires a look at the initial commitments and the underlying geopolitical frictions.
The Core Terms of the Peace Agreement
On 17 June, US President Donald Trump and Iranian President Masoud Pezeshkian signed a 14-point Memorandum of Understanding (MoU), aimed at establishing a 60-day window to negotiate a comprehensive settlement. Three primary pillars defined the deal:
- Unrestricted Transit in Hormuz: Iran committed to ensuring safe passage for commercial shipping through the Strait without imposing fees for 60 days. This was to be managed in coordination with Oman, alongside a commitment to clear mines and technical obstacles from the shipping lanes within 30 days.
- $300 billion Economic Package: A reconstruction package totaling $300 billion was pledged by the US and Gulf nations to support Iran, with the framework to be finalized during the negotiation period.
- Nuclear Dialogue: Iran agreed to halt the development of new nuclear weaponry, with both nations set to create a framework for managing the existing enriched uranium stockpiles.
Motivations Behind the Iranian Aggression
Tehran’s primary driver for the attacks appears to be a desperate bid to maintain hegemony over the Strait of Hormuz. Iran had attempted to mandate a new, coastline-adjacent shipping corridor and required vessels to register with the newly established Hormuz Transit Authority, a move seen as a precursor to collecting transit levies. When Oman introduced an alternative route on 24 June, the Islamic Revolutionary Guard Corps (IRGC) retaliated with warnings, viewing the move as a challenge to their authority. According to maritime analytics from Kpler, daily vessel traffic through the Strait has plummeted from over 100 to roughly 30-40, reflecting the heightened instability.
Analysts also point to external pressures. Professor Vali Nasr suggests that the US-brokered Lebanon-Israel deal made Tehran fear a concerted American effort to diminish its regional influence. Simultaneously, reports indicated that the promised $300 billion funding package was being pared down, leading to the perception in Tehran that the agreement was a strategic deception. For Iran, the attacks were a calculated, albeit dangerous, display of strength designed to force a return to the negotiating table on their terms.
Why the US Responded Forcefully
The US maintains a long-standing policy under the Freedom of Navigation Programme to protect global maritime chokepoints. With approximately 52% of the world’s crude oil trade flowing through such narrow passages, including the Panama and Suez Canals, Washington fears that allowing Iran to impose tolls would set a dangerous global precedent. This concern was amplified by suggestions from figures like Indonesia’s Finance Minister Purbaya Yudhi Sadewa in April 2026, regarding potential tolls in the Strait of Malacca. To the US, Iranian control of Hormuz is not just a regional dispute but a threat to the architecture of global commerce.
The Collapse of Diplomacy
The US-Iran agreement was fundamentally flawed from the outset, lacking specific mechanisms for monitoring and accountability. As noted by expert Mark Champion, the intentionally vague language failed to resolve critical issues like missile capabilities and the permanent status of sanctions. While the US initially suspended sanctions on Iranian oil, the Treasury Department rescinded this relief after just 20 days. According to John B. Alterman, the failure to address the root causes of the conflict ensured that the deal was fragile. Following the US strikes on 8 July, and subsequent Iranian retaliatory fire toward military sites in Bahrain and Kuwait, the region remains on the precipice. While Donald Trump has threatened a blockade of Hormuz, the possibility of renewed talks mediated by Pakistan suggests that neither side may yet want a full-scale war, though the deep-seated mistrust makes a lasting solution increasingly unlikely.
