Russian Military Campaign Update - December 26, 2025

Russia's Deputy Foreign Minister Sergei Ryabkov stated that Russia will not sign peace agreements in Ukraine now and is demanding that any deal address its 2021 NATO ultimatums, including security guarantees and NATO's rollback. Meanwhile, Ukrainian forces are making tactical gains, especially in Kupyansk, despite Russian disinformation and false reports about battlefield successes. Russia continues to focus on offensive operations in eastern Ukraine, using concentrated forces and new drone units, while Ukraine prepares for a potential referendum and continues strikes against Russian infrastructure. The situation remains complex, with ongoing negotiations, military advances, and strategic shifts.
