## Prediction

Over the next month, the unresolved Hormuz closure and Iranian insurance regime will prompt a sustained US and allied naval buildup in and around the Gulf, including additional carrier strike group presence and expanded convoy operations. As IRGC forces test boundaries with close approaches, electronic harassment, and boarding attempts, both sides will continually refine rules of engagement, increasing the chance of an incident involving shots fired, disabled boats, or a briefly seized commercial vessel. Such an episode could rapidly escalate to limited kinetic exchanges before political channels reassert control. Confirmation would be announced or observed reinforcement of naval assets and documented near‑miss incidents; denial would be a negotiated de‑tensioning that reduces both the Iranian enforcement posture and Western presence.

## Drivers

- Iran’s de facto closure of Hormuz and creation of a quasi‑regulated corridor
- US President’s threat to "take over" the Strait and "hit Iran very hard again"
- Historical pattern of naval brinkmanship during Gulf crises
