## Prediction

Within seven days, the U.S. is likely to announce or operationalize an ad‑hoc naval coalition with European and regional partners aimed at protecting shipping through the Strait of Hormuz and Bab el‑Mandeb. The coalition will emphasize freedom of navigation and defensive escort missions, while carefully avoiding language that commits to offensive strikes on Iranian or Houthi assets. This matters because it internationalizes the confrontation, dilutes Iran’s ability to frame it as purely bilateral with Washington, and risks drawing more states into any escalation. Confirmation would be a Pentagon or allied announcement of a named maritime security operation; denial would be continued unilateral U.S. presence without coalition framing.

## Drivers

- Escalating Iranian threats to U.S. ships and firms across the Indian Ocean
- Yemeni forces’ control of Bab el-Mandeb and UN/GCC condemnation of Houthi attacks
- U.S. embassy warnings of escalation and airspace disruption
- Historical precedent of coalitions like Operation Sentinel and Prosperity Guardian
