Such operation can't be performed by amateurs from a rented yacht. It requires experience and resources available only to few countries on Earth.
Also, it was just a version published by Western media without any hard evidence.
> Sorry, but those are ALL mistakes made by Germans themselves.
It's not possible to tell if they are unless there's an investigation, but there would be never such an investigation because Germany is an occupied country for 78 years.
It's quite clear from the consequences, that Olaf Sholz, Annalena Baerbock, and other German politics do things that affect German industry and economics negatively at the same time improving US economy and making Germany more dependent on US.
Let me just say one thing: It doesn't necessarily take the US for German leadership to shoot their feet.
> USA had blown up the pipelines delivering cheap energy from Russia
Well, did they? I know this theory but AFAIK they could trace it back to some people in Ukrainian military. Western secret services (afair from Netherlands) even warned them twice that this was being planned but they didn’t react.
> USA is deliberately suffocating German economy.
Sorry, but those are ALL mistakes made by Germans themselves. They have been cheating, they have been lobbying the German governments to ease transformation cost for short-sighted profit, the (conservative) German governments acted to slow down renewables while quitting nuclear power earlier than planned. I think it’s not a coincidence that Putin started the war on Ukraine just at the time, Germany phased out its last nuclear power plants. It’s all stupidity on the German side, esp. when Merkel is still claiming that “she always knew who Putin really was”.
