Sweden detected 2 explosions equivalent to 100 toms of dynamite the moment the pipelines ruptured. And they found 4 separate leaks. If one rupture occurred then a leak might be plausible. Also-the day after the nord stream 2 was taken out, the new Norway-Poland Baltic Pipeline opened which does an end around Russia delivering gas to Europe. Who had motive to take out nord stream?Who knows? It really just could have been a rupture. Pressurized pipes can fail with a pretty big bang. So it just could be a coincidence. They happen too.
