Leading US journalist made the highly plausible claim a few weeks back that the US blew up the Nord Stream pipelines, because Joe Biden, or those who control him, were not happy with the level of support Germany was delivering. Maybe so, but his previous explanation, that cutting off of Germany from the Russian supply of energy, seems to be more important, since, unlike the support hypothesis, restricting energy has real teeth and has pulled Germany back into the line defined by the US. Biden warned during a press conference on February 7 that “if Russia invades… there will no longer be a Nord Stream 2. We will bring an end to it.” It is hard to think of a more revealing statement, one which promises what they will do, and did in fact do.
