Russia does not really need anything Europe has, because Russia can buy what Europe sells them elsewhere. But Europeans would freeze their butts in winter without Russian gas & oil.
“But Europeans would freeze their butts in winter without Russian gas & oil.”
Europe needs a dose of reality. They have shut down nuclear plants even though there were no problems with them and they had decades of service left...because, liberalism. They have practically done away with coal, because liberalism. This may help the various governments move back to sanity. Having people freeze to death has a way of doing that.
As another point, the US is taking over from Russia as an energy supplier. This will be good for the US economy.
If you want your economy to grow like a weed, lower the cost of energy. There is a one to one relationship between growth and energy cost.
