Have been reading that every inch of this sea is monitored by NATO. Besides surface vessels, NATO has undersea drones and regular air patrols and surface vessels constantly in the area.
Its close to Denmark, and is entry/exit choke point for every Russian ship and sub in the Black Sea, so its closely watched - has been since the Cold War.
So its nearly inconceivable NATO/USA doesn’t know who did it.
Thats because the US did it. This is as clear as a summer day in San Diego.
Who is running the U.S. Government? Why that would be figurehead President Joe Biden and staff from the Obama/Biden administration. The same administration who worked with Facebook to overthrow the Egyptian Government and help install the Muslim Brotherhood. The Obama/Biden Administration also oversaw disastrous policies in Libya that sent copious weapons to the Libyan rebels who killed our Ambassador Stevens. The Obama/Biden regime refused to rescue the people they sent to the US CIA outpost in Benghazi, Libya, resulting in 4 needless deaths and many injuries. The abandoned Americans had to find their own way out of country to America. When they arrived home the Obama/Biden administration required them to sign non disclosure agreements.
So who destroyed the Nordstrom pipeline? My best educated guess would be the Biden Administration since the same people were involved in instigating prior wars. IMO World War 3 is in progress.
