But hacking is up!

Are there not other bad actor(s) mostly aligned with Putin who could start buying u all their oil if say a war broke out, or are we passed that type of war needing so much such natural resources, or perhaps those countries have enough oil reserves/production already?

This is just a guess, but the former Soviet union countries that potentially would re-align with Russia aren't huge countries with big oil appetites. They likely don't have the means to start buying up billions of dollars in Russian oil.
