It was obviously the west, some combo of Brits, US, and Poland.
The design was to prevent freezing Germany demanding an end to the war and dropping sanctions. Now they can’t.
The question is what will the response be? Looking for serious cyber attacks. This could get very bad.
Well, at least when they take down the US power grid and kill off millions to complete the next phase of the Great Reset it can be blamed on Russian cyberattacks.
it is such a machiavellian act - permanent harm to german economy and industry. remove likelihood that they would buckle and agree to start NS2 this winter - this is also a large loss of leverage for russia due to same. and with western media so willing to carry a narrative, blame russia, with a fair amount of the western population willing and able to believe them.
assuming there is a non-radioactive world down the line, it will be interesting to see if Germany pivots once they can get out of the current mess.
