The Financial Times reported the information.Several Ukrainian and U.S. officials familiar with this campaign said American intelligence has enabled Ukrainian forces to strike critical Russian energy sites, including oil refineries far from the front lines.This support, which intensified from mid-summer, had not been previously reported.The shift came after a phone call between Donald Trump and Volodymyr Zelenskyy in July, during which, according to FT, the U.S. president asked whether Ukraine could strike Moscow if Washington provided long-range weapons.Trump reportedly expressed support for a strategy intended to “make them [the Russians] feel pain” and push the Kremlin toward negotiations, according to two sources familiar with the conversation. The White House later said Trump “was simply asking a question, not encouraging further killings.”Officials familiar with the matter said U.S. intelligence assists Kyiv in planning flight paths, altitude, timing, and mission decisions, enabling Ukrainian long-range drones to avoid Russian air defenses.Three people familiar with the operation said Washington was closely involved in all stages of planning. A U.S. official said Ukraine selected targets for strikes, after which Washington provided intelligence on the vulnerabilities of those sites.Other sources involved in the operations said the U.S. also identified priority targets for Ukraine. One described Ukrainian drones as a “tool” for Washington to weaken Russia’s economy and push Putin toward an agreement.Trump had openly expressed frustration with Putin since hosting the Russian leader at the Alaska summit, which yielded little progress. According to sources, this also influenced Trump’s support for long-range strikes.On October 11, Ukrainian President Volodymyr Zelenskyy spoke by phone with U.S. President Donald Trump to discuss Russia’s recent large-scale attack on Ukraine’s energy infrastructure.
