**Deck**: Iran has suspended all commitments under a Pakistan-brokered memorandum of understanding, accusing the U.S. of violating the deal with strikes on Iranian infrastructure. With Tehran’s envoy saying Iran is “officially resuming war” and health officials citing dozens killed, the collapse of the Islamabad channel removes one of the few remaining diplomatic guardrails on U.S.–Iran confrontation.

One of the last formal guardrails on U.S.–Iran tensions has been stripped away, as Tehran declares it is "officially" back at war and suspends its commitments under a Pakistan-brokered memorandum of understanding that was meant to keep a lid on escalation.

On 18 July, Iranian Deputy Foreign Minister Kazem Gharibabadi said Iran had stopped fulfilling the commitments in a memorandum of understanding signed in Islamabad, asserting that the United States had "violated and suspended all its commitments" under the same framework. "We have also suspended our commitments... and we are busy defending the country," he said. A separate statement from Iran’s ambassador to Pakistan went further in political tone, saying Iran was "officially resuming war" following U.S. attacks on its infrastructure.

The precise contents of the Islamabad memorandum have not been fully disclosed, but both Iranian and regional commentary suggest it functioned as an understanding aimed at limiting direct confrontation between U.S. and Iranian forces, including through Pakistani mediation. Tehran now argues that recent U.S. strikes on Iranian infrastructure, particularly in the south and center of the country, amount to a clear breach. Reports describe American attacks on bridges, tunnels, military installations, and other infrastructure, with a concentration on transport routes to the strategic port of Bandar Abbas.

Iran’s Health Ministry has put a grim human figure on those strikes, saying that over the past three weeks 50 people have been killed and 500 wounded in U.S. attacks on Iranian territory. Those numbers cannot be independently verified, and Washington has not issued a detailed public casualty count. But even as claims, they serve a domestic purpose: to justify Iran’s decision to step away from negotiated constraints and present its response as defensive rather than escalatory.

For ordinary Iranians, the implications are tangible. Transport corridors around Bandar Abbas and other southern hubs are central to domestic trade and fuel distribution, not just military logistics. Bridges and tunnels linking interior regions to the coast support everything from food deliveries to labor commuting. Bombing those routes risks disrupting supply chains, raising prices, and deepening the sense of siege among civilians who may already be grappling with sanctions and economic strain.

Externally, the collapse of the Islamabad MoU removes a key deconfliction channel at precisely the moment when Iranian forces are visibly striking back across the region. The Islamic Revolutionary Guard Corps has publicly claimed ballistic missile and drone attacks on U.S. bases and associated targets in several countries, while Iranian strikes have hit facilities in Kuwait and Kurdish militia positions near Sulaymaniyah in Iraq. With Tehran no longer bound—even nominally—by a confidence-building framework, each additional U.S. or Iranian strike carries a higher risk of miscalculation.

Strategically, Iran’s announcements are an attempt to recast the rules of engagement. By declaring that a diplomatic mechanism has failed due to U.S. actions, Tehran is signaling to regional states and global powers that further Iranian attacks on U.S. forces or partners are, in its view, the natural consequence of Washington’s choices. This framing is aimed at shifting blame for any coming escalation and complicating U.S. efforts to keep partners aligned.

For Pakistan, the unraveling of the MoU is a setback to its quiet role as a broker in one of the world’s most volatile rivalries. It also highlights the limits of mid-level understandings in the absence of a broader political settlement: when either party decides that strategic costs outweigh diplomatic benefits, such deals can vanish almost overnight.

The broader lesson is that in a confrontation already rich with drones, missiles, and proxy forces, even thin diplomatic scaffolding matters. When Tehran says it has "resumed war," it is less a legal declaration than a political statement that restraint mechanisms are being downgraded in favor of open-ended retaliation.

The next indicators to watch are whether Washington acknowledges or contests Iran’s interpretation of the Islamabad MoU, whether Pakistan attempts to re-engage as a mediator, and how quickly Iran’s promised "defense" manifests in new strikes on U.S. assets or partners. Any move by either side to publicly redefine red lines—such as explicit warnings over future infrastructure attacks—will shape how far and how fast this newly unconstrained phase of the confrontation runs.
