## Prediction

Within 24 hours, both US and Iranian forces are likely to increase visible naval and air patrols around the Strait of Hormuz, including ISR flights and maritime escort patterns, but stop short of deliberate kinetic engagement. This posture hardening aims to deter further drone shootdowns and tanker strikes while signaling resolve to domestic and foreign audiences. Commercial shipping will face more hails, shadowing, and potential inspection threats, increasing stress on crews and operators. Confirmation would be additional CENTCOM and IRGC media releases showing warships, drones, or missile units in the area and reports of more frequent close encounters; denial would be a rapid, negotiated deconfliction announcement and visible stand-down of patrol intensity.

## Drivers

- IRGC claims downing of US MQ-1 over Strait of Hormuz
- Recent tanker projectile strike in Hormuz injuring crew
- IRGC warning to 'change geography of war' if US strikes again
- Persistent CENTCOM theater tension and drone incidents
