If you look at the volumes of russian oil and gas exports since 1986
it looks like Russia is at the very top of the food chain
Today Russia is number one oil exporter with the export volume on top of Saudi Arabia
Europe is consuming like 40% of its natural gas from Russia
when oil price reaches $100 ruski make on export of oil and n-gas one billion dollars a day
with the economy of 1.2 tril in GDP this is big for them
None of which negates the facts of your post that Europe is rife with nuclear reactors in spite of the Soviets cunning plan. LOL
