Without Russians sources of energy West is nothing! If the other world will come to our side, I don't envy the West. Now it will be another game. You've asked for that.
Like coal? Sorry, if You want to tell me that west can't endure one winter with heat problems... Well. Humanity is lost.
But it's something what will stabilize soon - gas, coal, everything.
And I am optimist sometimes, so... I see really good potential here. Maybe some countries or whole mentality of west will wake up, and they will never again makes their countries so dependent of another country.
