## Prediction

Over the next 30 days, the U.S. strike on an Iranian tanker near Kharg is likely to evolve into a sustained pattern of U.S. and IRGC naval forces shadowing each other and conducting intermittent close encounters throughout the Gulf. While both sides will likely avoid large-scale exchange of fire, periodic incidents—boarding attempts, UAV overflights, warning shots—will normalize a chronically high-risk environment for commercial shipping. This persistent friction will tie down U.S. naval assets, embolden hardliners in Tehran, and increase the probability of an accident or miscalculated engagement that abruptly escalates. Confirmation would be multiple documented naval incidents or unsafe approaches per month; a formal deconfliction agreement or mini-deal on maritime conduct would shift the trajectory.

## Drivers

- Direct U.S. kinetic strike on Iranian tanker inside Iran’s maritime approaches
- Emerging trend: intensifying contest over energy routes and Hormuz anxieties
- Historical patterns of IRGC harassment campaigns after major confrontations
- Lack of stable diplomatic framework between Washington and Tehran
