Ukraine's advanced drone warfare is significantly impacting Russia by destroying oil refineries and disrupting battlefield supplies. President Zelensky announced a "40-day influence operation" aimed at forcing Russia into peace negotiations. This followed one of the largest drone attacks, hitting 12 Russian regions and Crimea. Russian authorities claimed to intercept hundreds of drones, though explosions were reported at a chemical plant. A major Moscow refinery, hit a week prior, is expected to be offline until 2027, with other refineries also targeted. Zelensky declared that if Ukraine suffers, Russia will too, citing Putin's refusal to negotiate a dignified peace. Putin acknowledges the damage but believes the strikes won't divide Russian society. Former President Trump, after meeting Zelensky and speaking with Putin, commented that Ukraine is performing well militarily. Trump reportedly expressed frustration with Putin and even hinted at withdrawing from prior understandings regarding Ukraine's Donbas region. U.S.-led Ukraine diplomacy has been hindered by ongoing global conflicts and past negotiation failures. The effectiveness of Zelensky's drone campaign in restarting peace talks remains uncertain, with some analysts suggesting it might harden Russian resolve. The drone strikes are particularly impactful in Russian-occupied Crimea, leading to fuel sales halts and a state of emergency. Ukraine is also employing drones to disrupt Russian troop supply lines along the front lines.
