Ok this might be a counter-conspiracy thingie...

Because originally the conspiracy was that that the US had taken out Nordstream to force the Germans to stop buying energy from the Russians. And I really did think that was plausible given it made little sense to me why Russia would blow up it's own pipeline...

But now that the Russians are proposing to pipe all their gas through Turkey, I'm wondering if it could have been the Russians sabotaging their own pipeline in order to make Turkey the new Germany and really upending the power balance in Europe
