I mean, its not like Biden didn't make the statement that he'd do exactly this. If him admitting that it was a plan isn't enough for you, I don't think your myopia is going to be altered by any further discussion.
I'm saying that the thing about being an armchair politico on a forum and not a member of an Alphabet Soup organization is that unless someone claims responsibility we won't know who actually did it until maybe a half-decade to a decade out when all investigations are concluded and the various international intelligence agencies and private journalists get the story straight.
They were very certain France hacked NASA until they weren't.
(Something like Biden's loose lips is only further cover for another cloak-and-dagger actor, state or private. Until and unless some country or group comes right out and claims responsibility, all manner of idea-tossing on this forum doesn't give us more than a well-shaped question mark on who actually did it).
Policy hasn't worked, in years. In spite of the US' worst efforts, Nord Stream was built and completed and could actually be used to peacefully engage in energy economy between Russia and Europe.
This alliance is intolerable to the USA, so: the last act was destruction.
Lets see, anyway. Evidence is going to be important on this case.
