I don’t care either way who blew up the pipeline but to me the biggest glaring reason why I don’t think it’s the US is because Russia did not retaliate in any meaningful way.
Us peons are clueless about what happened but Russia knows and they would know if it was them. If it wasn’t them then it’s obvious who did It and escalating the war would be justified. The fact this didn’t happen to me suggests it was Russia all along.
