6. The US has for months been helping Ukraine mount long-range strikes on Russian energy facilities, in what officials say is a co-ordinated effort to weaken Vladimir Putin’s economy and force him to the negotiating table. American intelligence shared with Kyiv has enabled strikes on important Russian energy assets including oil refineries far beyond the frontline, according to multiple Ukrainian and US officials familiar with the campaign. The previously unreported support has intensified since midsummer and has been crucial in helping Ukraine carry out attacks that Joe Biden’s White House discouraged. Kyiv’s strikes have driven up energy prices in Russia and prompted Moscow to cut diesel exports and import fuel. The intelligence sharing is the latest sign that Trump has deepened his support for Ukraine as his frustration with Russia has grown. (Source: ft.com)
