It's like going back and forth in my opinion, Europe doesn't want to be cold and of course it needs gas there on the other hand they also definitely want to have an effect on Russia but indeed Putin is not that shallow and he has thought about this carefully.
Well this is quite a difficult thing because indeed Putin and Russia have the resources needed and it is very difficult to criticize if they still need it
Gas is a major need because of the weather condition , the weather in winter is very cold and heater is a big necessity as the terrain get frezen. Sourcing for alternative is the solution although maybe at a higher price because Putin is definitely using this as an advantage.
They need to determine the price now regardless of the sanctions they impose because still Russia is in control now and when they don't want to follow Russia then indeed the Gas deal may not happen and indirectly this could slowly kill them because of the weather .
They can't do much because Russia is still in control because maybe now it will be like this, Russia can distribute gas but with the rules and powers they make.
