It was more proof of the moral bankruptcy of modern russia....
We didn't bomb Ukraine's energy grid for close to a year (from the spring of 2023 to the spring of 2024 roughly)... so much so, that their Minister of Energy was going around boasting that the winter of 2024-2025 is "secured".
Ukraine then finished its work on some long range drones (essentially Cessnas with remote controls), and started torching our oil refineries and storage centers. At the peak, they disabled something like 14% of Russia's refining capacity.
Then we wrecked a further 20% of their energy grid in response, and the forecast for winter again turned very gloomy. This gave start to those secret negotiations I mentioned, in Turkey.
The negotiations faltered at different points, but in recent weeks it looked like it was actually going to result in an agreement.
Then Biden authorized use of ATACMS, Ukraine started hitting our stuff deep behind the frontline again, and the rest if known.
