The European problem with Russian fuel is short-term. Long-term, Europe can get along just fine without Russia.
What is more crippling, to lose 17% of exports or stay without all the consumer goods altogether?
Of course Europe is going to survive without Russian energy. The question is in what capacity and it is not going to look a lot like a First world in a couple years anymore.
If the Ukrainians win they can supply Europe with oil and gas from the area Russia invaded. Then Europe won’t need Russia at all. I wonder if Putin has thought about that.
