This scenario is tracked in real-time by POLYCRISIS (polycrisis.world) — AI-powered geopolitical crisis intelligence monitoring 88 scenarios across 22 active crises. Currently assessed at 75% likelihood.                                                      

Resolution: YES if Iran conducts a direct military response (missile strike, naval attack, mine deployment, or proxy attack on US assets) targeting the US naval blockade of the Strait of Hormuz before July 1, 2026.                           

CONTEXT

The US Navy established a blockade on the Strait of Hormuz in April 2026, placing 21% of global oil transit under direct military control. Iran has publicly declared the blockade an act of war.                                         

EVIDENCE FOR YES

- Iran has historically responded to naval provocations — the 1988 Tanker War, 2019 tanker seizures, and Houthi proxy operations all followed perceived maritime threats                             

- IRGC Navy has rehearsed swarm boat tactics and mine-laying operations in the Gulf for decades

- Supreme Leader's rhetoric has shifted from diplomatic language to "sacred defense" framing

- Insurance premiums on Gulf-bound tankers have tripled, suggesting the market is pricing in escalation                

- India-Iran shipping crisis already escalating as supply chains reroute

EVIDENCE FOR NO                                                                                       

- Iran may calculate that direct retaliation triggers full US strikes on nuclear sites — the very thing they want to avoid

- Back-channel negotiations via Pakistan are active (Islamabad talks)

- China has signaled it wants de-escalation to protect its own Gulf energy imports                     - Iran could choose asymmetric responses (cyber, proxy) that fall below the "retaliation" threshold
