Well if you want to consider motives, what I said makes a clear motive IF Russia did it, for them to leave one of the NS2 pipes untouched doesn't it. Because the history was of Russia trying to blackmail Germany and get Germany to turn on NS2.
But I didn't claim Russia did it. You know you can suspect the US did it but that doesn't mean you need to promote fake made up stories that defy scrutiny to believe it. You can still search for the actual truth and want to see actual facts presented rather than fiction.
