we still dont know fuck shit about nordstream, it's theorized that it was ukraine, but we don't exactly have super solid evidence of this. it could've been russia, but let's be real. It probably wasn't. It could've been china, but i doubt that they cared. Could've been the US, i sincerely doubt this. Could've been one of the european nations, or maybe just a rich billionaire or some shit, who knows.
What we do know, is that the attack was for all four of the pipelines, and one of them failed to properly destroy the pipeline, so presumably there is some amount of forensic evidence there. And it seems like nobody really wants to talk about it for fears of starting ww3
During a joint press conference with German Chancellor Olaf Scholz, President Biden is asked about the Nord Stream 2 pipeline.
"If Russia invades, that means tanks or troops crossing the border of Ukraine again, then there will no longer be a Nord Stream 2. We will bring an end to it."
when asked how, the president says, "I promise you, we will be able to do that."
