This is nothing. The Russian will is unbreakable.
Besides the fact that Russian will has been broken by Swedes (1617), Finns (1918), Baltics (1583), Lithuanians (1919), Estonians(1918), Latvians (1920), Poles (1921), Turks (1681), Georgians (1920), Afganis (1989), a bunch of 'stani's I don't feel like looking up, Mongols (14th century in general), Chinese (1652), Japanese (1905), Germans (1917) and the goddamn French (1856), this statement is somewhat true.
Gas is mostly used for heating, not electricity, also as fuel and in some industries. Some EU countries are 100% dependent on Russia for their gas supply, in Germany it's 35% (and 36% for oil). In Germany, heating in almost 50% of homes depends on gas, almost 30% on oil, electricity accounts for just 5,4%.
The small baltics might be completely dependent on the Russians but most of the Russian market isn't countries that can't cope. Russia only accounts for 25% of overall European natural gas use.
You scaring shits out of me My family lost all bank savings in 90s and parents wages was delayed up to 14-16 months at peak. Guess what, we still here. You really understimate endurance and little needs of slavs, thats biggest mistake West usually tends to make.
Besides, some EU countries completely depend on our gas (liek Poland is 92% or something) and belt of mediterranean countries quite dependant on our tourists money (it's millions of ppl a year). There is much more to that list but I cba to provide links, because any prooflinks is going to be ignored or refuted anyways.
Poland is even less dependent on natural gas then Europe's average, primarily because they are a major coal producer and use much more coal. So they "liek" gonna be glad to see a trade war with Russia because that would help their own economy through better coal prices.
I don't really care if you are scared or not. The numbers don't really care either. But a simple back of the envelope calculation says that a complete interdiction of Russian imports and exports with Europe would result in a single year 10% GDP reduction from first order effects alone (not counting economic fallout) which could reasonably be extrapolated to the Russian unemployment rate hitting 25%. I'm sure that an economic collapse worse then the great depression will be no match for Russian indomitable spirit.
