My thought was the area where the pipeline damage occurred was not Russian territorial waters, it was Denmark’s territory. A NATO founding member.
Russia would not want NATO to enter the war in Eastern Europe by committing an act of war against a NATO member state.
Secondly, why would Russia damage their own source of wealth?
This was not Russia.
I don’t think it was Russia, either. I think it was the U.S. Navy underwater demolition crew under Biden’s orders.
