Sure they were chasing a sub in shallow water. Have you ever been to the Baltic Sea? Denmark? A sub can’t hide there, it’s shallow. And.......There is nothing to be gained by the Russians blowing up their own pipeline, something that is a major source of income for them. No, there is only one person/actor/nation that wants to push Russia into total submission, and that is Biden and the US. And they do it for the world bank and to protect the US Dollar. And the proxy war with Russia in Ukraine isn’t going as fast as they want it to. So the US upped the game, pissed off Europe and now are trying to blame Russia. Europe is going to sue us into oblivion once it is exposed we did this to them
First off, it wasn't their pipeline anymore: Germany nationalized the Gazprom holding companies that owned the pipelines several days ago. This was partially payback.
Second, the US regime wears diapers because it pisses itself with fear, just like the Obama regime. It would never undertake such a bold action.
Third, even if the US did it, it affects mainly Germany and no one in Europe gives a crap about Germany. And in any case, given the Ukraine war, the Europeans are hardly going to separate from the US.
