## Prediction

Over the next seven days, the U.S. and Iran are likely to maintain a tense naval standoff in the northern Arabian Sea and Gulf of Oman, with expanded patrols, overflights, and near-miss encounters. The U.S. will likely surge additional surface combatants, submarines, and ISR assets, while Iran disperses missile launchers and small craft to complicate targeting. This posture will deter immediate full-scale conflict but increase the probability of miscalculation, including accidental engagements with commercial shipping or third-country navies. Confirmation: additional U.S. carrier/strike group presence announcements and IRGC footage of shadowing U.S. ships; denial: rapid negotiated de-escalation and visible drawdown of forces.

## Drivers

- IRGC claims of ballistic missile hits on U.S. destroyers
- U.S. destruction of five IRGC-linked tankers in the same theater
- Emerging trend of Iran targeting U.S. unmanned systems near Hormuz
- Historical pattern of extended standoffs after initial Gulf incidents
