If you're talking about "outside threats to oil supply" then this has to be a major and current example: https://en.wikipedia.org/wiki/2025%E2%80%932026_Russian_fuel_crisis https://en.wikipedia.org/wiki/2025%E2%80%932026_Russian_fuel... We can find many examples of "Russian oil refinery damaged by Ukrainian drone strike" e.g. today https://www.kyivpost.com/post/82326 https://www.kyivpost.com/post/82326 > repairs potentially taking up to six months. The strike adds to Kyiv’s escalating campaign against Russia’s oil industry and a growing fuel crunch across the country. But search again tomorrow and there will be new examples. Refineries and other oil infrastructure are large, located in well-known fixed locations and are highly flammable. This campaign demonstrates what a weak spot they are for a petrostate.
