## Prediction

Within 7 days, Iran’s shift to a fully offensive posture and the ongoing blockade of Hormuz will drive both Iranian and U.S./allied naval forces toward more aggressive rules of engagement, making at least one dangerous close encounter or warning-fire incident highly likely. Iranian fast boats, drones, or coastal missiles may approach or lock onto U.S.-flagged or allied tankers and warships, prompting deterrent actions that could include disabling shots or the seizure of smaller Iranian assets. Such a confrontation would signal that the crisis is moving beyond signaling into the kinetic danger zone, complicating any later diplomatic off-ramp. Confirmation would be reports of “unsafe and unprofessional” maneuvers escalating to shots fired or forced boardings; denial would be quietly negotiated tacit understandings that keep interactions cautious and reversible.

## Drivers

- Iran’s declared offensive posture and ultimatum to lift the naval blockade
- Existing U.S. naval focus shifting from Asia to the Gulf
- Locked-in Hormuz blockade with no diplomatic progress
- Historical pattern of IRGC harassment during periods of high tension
