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.
My two cents
The American sanctions are harming Europe more than Russia. Russia is still selling oil and gas to many other countries.
Due to all the protests and conversations in nations parliament's to ignore the sanctions and use the oil to save our economies. To do that would mean that EU nations would need to shit up and not seek war with Russia over Ukraine, which is one of the best scenarios for Russia.
America and globalists elites can't allow that to happen they need this war with Russia for various reasons. They're also scared if they let Russia off the hook easily Russia will expose them to the world about what they were doing and planning in Ukraine.
