One has to ask... Cui bono?
"Accusations of Russian involvement in the bombings lack all credibility and detract from the far more likely perpetrator: the United States. The first question that has to be asked about the Nord Stream bombing is: Cui bono? Who benefits, and who had the motive to carry it out?
Russia had no motive to destroy the Nord Stream pipeline. Russia’s Gazprom conglomerate owned half of the pipeline, alongside German, French and Dutch shareholders, and the pipeline was at the heart of Moscow’s plans to rebuild economic ties with Europe, if and when the war with NATO in Ukraine ended. It had no reason to blow up its own pipeline.
For Washington, the bombing presented two benefits. Firstly, coming amid the NATO military escalation against Russia in Ukraine, it would help fuel more anti-Russian war propaganda. Secondly, by making Europe more dependent on US natural gas imports to replace Russian gas, it corresponded to a major US aim in the Ukraine war from the outset: to bring Europe more firmly under US control. These aims have increasingly come into the open in recent years."
