Re: Nordstream
Either US or Ukraine. Hersh reported it was the US, & he has a track record of exposing US lies. Plus, many US officials publicly threatened that pipeline.
I don't trust Putin, but he's not stupid enough to blow up his money line. Plus, if it were intact, it'd give him negotiation leverage.
I saw the story pointing at Ukraine, but that indicated they would've needed US assistance to pull it off.
