Iran Iran Update Special Report, July 21, 2026
understandingwar.orgKey Takeaways
The Houthis likely decided to impose their blockade on Saudi Arabia to advance their own interests, though Iran probably encouraged them to impose the blockade for Tehran’s own purposes. The Houthis have repeatedly warned Saudi-owned ships against transiting the Red Sea via radio on July 20 and July 21.
The Houthis only threatened shipping in the Red Sea once it benefited Houthi objectives. The Houthis did not adhere to earlier Iranian calls in July to close the Bab al Mandeb Strait during the recent conflict and only decided to impose a blockade on Saudi Arabia on July 20 following Saudi strikes on Sanaa International Airport on July 13.
Iran continues to use force to impose its control over the Strait of Hormuz and compel vessels to follow Iranian transit restrictions. Iran rejects any alternative to its designated traffic separation scheme, particularly the southern Omani route, because it allows vessels to bypass Iranian authorization and directly undermines Iran’s claim to control maritime traffic through the strait.
Iran is repeatedly attacking US bases and personnel across the region in order to erode US willingness to challenge Iranian control over the Strait of Hormuz. Iran likely calculates that sustained attacks and rising US casualties will generate domestic pressure on the United States to end the conflict, force the United States to surrender, and accept Iranian control over the strait.
Iran is attacking critical infrastructure in Kuwait to impose direct civilian and economic costs on states that host US forces and pressure them to curtail US military operations. Iran likely calculates that sustained disruptions to electricity and water supplies will increase domestic pressure on Kuwait to restrict US operations from Kuwaiti territory.
