This really is a huge story, of course it's not getting the attention it deserves - oh look at the pretty balloons! The US is certainly responsible for the Nord Stream attack - cui bono? We can pose the same question with regards to Norway's alleged involvement, they stand to benefit as another large provider of gas to Europe. Also, the idea that Russia would bomb their own infrastructure is highly dubious and I think this is something most objective minds would agree with.
What we're looking at is an act of terrorism and an attack, not only on Russian, but German critical infrastructure. An obvious question that comes to mind is, does this attack invoke NATO article 5?
One last tidbit, maybe check the spelling of Hersh, in a few places it's written as 'Hirsh'. Cheers
