Ukrainian drone strikes on Russian fuel infrastructure are causing nationwide diesel and gasoline shortages across more than half of Russia's regions, which Putin has publicly acknowledged. This is acutely serious for Russia because international sanctions limit food imports and domestic agriculture depends on fuel — suspensions of farm operations would disrupt food security in a country already struggling with supply chains. The author correctly identifies this as a strategic vulnerability, though the broader picture includes that Russia maintains some fuel production capacity and has implemented export restrictions to mitigate shortages.
