"textContent": "The immediate danger in the Strait of Hormuz is obvious. The deeper problem may be that Iran’s official diplomats no longer appear to control the policy they present.\n\nThat is the significance of the sharp reversal between 17 and 18 April. Iran’s foreign minister, Abbas Araghchi, said the strait was open to commercial traffic. Within a day, the IRGC Navy had attacked commercial vessels, warned ships away, and helped reduce movement through the waterway to a trickle apart from Iranian traffic.\n\nUS Navy’s blockade of Iranian ports on the Strait of Hormuz, as of 18-Apr-2026. | DREAMSTIME/KORWEN (based on the data from the Institute for the Study of War and the Critical Threats Project)\n\nAn analysis by the _Institute for the Study of War_ and the _Critical Threats Project_ argues that this was more than a military escalation. It may also reflect a shift in power toward the Islamic Revolutionary Guards Corps and figures around Major General Ahmad Vahidi, at the expense of Iran’s formal negotiating channel.\n\nIf that reading is correct, the implications go beyond shipping disruption. It would mean outside powers are not simply facing a harder Iranian position. They may be dealing with a system in which the men speaking in negotiations are not fully in command of the decisions that matter.\n\nThat makes every proposal less reliable, every pause more fragile, and every diplomatic signal harder to trust.\n\n### **GOING FURTHER**\n\n * ###### Iran Update Special Report, April 18, 2026 | ISW\n\n * ###### Iran Revolutionary Guard fully closes Strait of Hormuz and fires on ships trying to pass | AP\n\n * ###### Iran says strait of Hormuz ‘completely open’ but sounds warning on US blockade | THE GUARDIAN\n\n * ###### Iran closes strait of Hormuz again ‘until US lifts blockade’ | THE GUARDIAN\n\n * ###### How to keep the Strait of Hormuz open in the long term | CHATHAM HOUSE\n\n\n\n\n\n\n\n###\n\n\n\n\n* * *\n\n#### **Sources:**\n\n###### ▪ This piece was first published in Europeans TODAY on 18 April 2026.\n\n###### ▪ **Cover:** Dreamstime/KORWEN.\n\n\n\n\n* * *\n\n\n",
