In 2023 - a full year into the war - Hersh asserted "the Russians have yet to put any of their main forces" into Ukraine (https://twitter.com/JimmySecUK/status/1628898816953909251). He's carried water for the Syrian regime repeatedly; the Nordstream report was pretty widely debunked by available open source intelligence. He's not super credible these days.
Hersh never provided ANY evidence and the german investigation is pretty conclusive that it was done by Ukrainians. Which is pretty understandable since the main and openly stated purpose of NS was always to circumvent Ukraine. That might be ok in peace time but when at war and your enemy tries to freeze you to death, things look differently.
2022 Pew
"85% of Americans and 77% of Germans see the relationship between their countries as good. This is consistent with recent years, though prior to President Joe Biden’s election in 2020, German views of the relationship were much more negative."
It was as high as 82% positive in 2022. During Trump's first term it was much lower but Trump is an outlier.

I find it more credible that these were the actors involved. Biden wanted to end a future link between Germany and Russia. In Germany there is significant segment of the population that is distrustful of the US (even before the recent Trump shenanigans) and the potential stronger infrastructure ties to Russia. I find it more credible than a ragtag group of Ukrainians did it personally.
Although the truth may never be known.
