The pipeline was blown up by NATO, something like using Poland but planned by US. There is too many holes in the "Russia blew up their own pipeline" idea.
Now here's the key... It wasn't the US being paranoid about Germany selling gas to Russia and going back their back and fucking their ally so they could keep in line. Germany was in on it! These NWO shitfucks are all in together on the Russia sanctions had no interest in wavering to stop their people from freezing to death. Germany didn't like the protestors so they asked the US to help shut them down by taking the pipeline out of the equation.
Apparently, Russia just wanted to spend $10 Billion of their own money building a pipeline, fill it with 300 Million cubic meters of natural gas ($600 Million worth) ... and then release all of that gas out to atmosphere and destroy the pipeline before it was ever used.
Russia must have just wanted to see what it was like to lose $11 Billion +/- in less than 10 seconds. :>)
