Selenskyj sees peace negotiation window before winter as Russia loses battlefield initiative.
Ukraine’s year-long drone campaign against Russian energy infrastructure has severely damaged Moscow’s oil refining capacity and military supply chains. President Wolodymyr Selenskyj announced the results of “Operation Spiderweb” on June 1, saying the campaign has fundamentally changed the war’s dynamics. Russian territorial gains have slowed to their lowest rate in three years, creating what Ukrainian officials see as an opportunity for peace negotiations before winter.
Drones Target Deep Inside Russia
Ukraine developed long-range drones over recent months that can strike thousands of kilometers into Russian territory. The campaign focuses on oil refineries and weapons factories. In May alone, Ukraine damaged 16 Russian refineries, including 8 of the 10 largest. Russian oil processing has fallen to its lowest level in over a decade.
Military Logistics Collapse
Selenskyj said Ukrainian forces can now strike Russian military supply lines across occupied territory. “For the occupier, there are practically no safe roads left in the south and east,” he stated. Supply shortages have hit Russian-held areas in eastern Ukraine and Crimea. Russian troops captured only 14 square kilometers in May, the lowest monthly gain in three years, according to Ukrainian military analysts.
Russia Faces Fuel Crisis
Russia imposed a kerosene export ban until November 30, 2026, and is now exploring imports of jet fuel JET A-1. Vice Prime Minister Alexander Nowak ordered energy and transport ministries to check whether fuel facilities can accept kerosene from domestic and foreign sources. The move signals Russia’s desperation to maintain aviation operations.
Window for Peace Talks Opens
Selenskyj told CBS that Russia has lost battlefield initiative since December 2025. He called for diplomatic talks before winter, saying “we have this timespan now.” Ukrainian Chief of Staff Kyrylo Budanow said a peace agreement before winter is “absolutely realistic.” Both officials expect a US delegation to visit Moscow and Kyiv soon. Selenskyj emphasized that Europe, including Britain, France, and Germany, must participate in negotiations.
Final Thoughts
Ukraine’s drone campaign has shifted the war’s balance by crippling Russian energy and logistics. With Russian territorial gains at their lowest in three years and Moscow facing fuel shortages, Ukrainian leaders see a narrow window for peace talks before winter weather returns.
