Within 5 years, 10 years at most, Europe will have transitioned far enough to renewables that energy is a lost cause as geopolitical tool. Then Russia truly is screwed.
Some of the former countries in the Soviet bloc which more readily faced this issue of Russia trying to extend it's sphere of influence to them they already solved it through more costly means.
Lithuania and Poland did not build LNG terminals because they provide cheap gas, they built them as a costly hedge against Russian use of gas supplies for political purpose like seen with Ukraine in 2005, 2007 and 2009. Which people seem to have forgotten.
