Ukrainian Commander-in-Chief Oleksandr Syrskyi stated on Dec. 9, 2025, that every citizen and soldier represents Ukraine's highest value, ordering unit withdrawals when defense loses meaning to preserve lives rather than fight for ruins, as shared in an X post by @UkrReview during the reporting window from 8:45 p.m. to 9:46 p.m. UTC. Syrskyi explained this approach accounts for the Russian army's slow advance, preferring to lose 200-300 meters of territory over one soldier's life, according to the X post. The statement underscores Ukraine's military tactics amid the ongoing conflict with Russia. Ukrenergo ordered additional de-energization of one sub-line from 00:00 to 06:00 on Dec. 10, 2025, as announced by Андрій Смолій, indicating further nighttime power shutdowns in Ukraine. Russian strategic aviation activities on Dec. 9 included training flights by five Tu-95MS from Ukrainka airfield and one Tu-22M3 from Shaykovka, landings of two Il-76MD at Rostov and An-26 aircraft at Voronezh and Levashovo airfields, and reconnaissance by one A-50U from Vladivostok, one Su-34R from Lipetsk-2, one Su-24MR from Khotilovo, and three Su-24MR from Morozovsk, per aviation monitoring reports shared in the window. No standard signs indicated Tu-95MS shelling that night, with a 1% probability noted. A source cited by RBC-Ukraine reported that U.S. President Donald Trump's team is urging a swift response from Ukraine on a peace plan, though Christmas is not the deadline, as posted during the past hour.
