## Prediction

Within 24 hours, Russia is likely to execute the "imminent" large-scale combined missile–drone strike President Zelensky warned of, focusing on Ukraine’s power substations, air defense nodes, and command centers. The attack will cause rolling blackouts, strain Patriot and other SAM batteries, and increase civilian casualties in major cities, especially if air defenses are saturated. This will test Western resolve on air defense resupply and strengthen arguments for local missile production inside Ukraine. Detection of large launch waves from Russia and Belarus plus widespread power and telecom outages would confirm this; a 24-hour period with only routine scattered strikes would contradict it.

## Drivers

- Zelensky’s specific warning of an imminent mass strike
- Recent Russian pattern of periodic large salvos
- Recent strike on Ovruch power substation and deeper attacks near NATO borders
