The US-Iran deal faces significant strain due to escalating tensions in the Strait of Hormuz. Iran has closed the strait, prompting US retaliatory strikes on Iranian targets. This cycle of attacks and counterattacks has severely damaged high-stakes diplomacy between the nations. Analysts suggest the US may be responsible for not adhering to the MoU's terms.

Clashing interpretations of vague memorandum of understanding language on Hormuz at heart of escalation, analysts say.

Recent flare-ups in hostilities between the nations in and around the Strait of Hormuz are threatening to capsize diplomatic negotiations.
