Of course NATO was surveilling the movements of Russian ships. Having said that, I believe Putin is capable of anything, but you are right it would be a bit stupid but so was invading Ukraine as well....
Invading Ukraine makes sense for Russia. While I think Putin miscalculated, in terms of maybe thinking Ukraine would fold after a few weeks of war or underestimating how much NATO countries would support Ukraine, I don’t see his invasion as without a rational motive.
Blowing up his own pipelines makes zero sense for Russia. The war in Ukraine makes some sense. If nothing else, a divided Ukraine prevents them from joining NATO.
OTOH, the US has long wanted to get Europe to stop importing so much Russian energy. The pipeline sabotage plays into our long-term geopolitical strategies, not Russia’s.
And this wouldn’t be the first pipeline the US has sabotaged. In the 1980’s the CIA sabotaged the Siberian pipeline. Google it…
