Gazprom, Russian gas monopoly, has on Kremlin’s orders first threatened to, and then suspended gas supplies to Europe in an attempt to blackmail it to stop supporting Ukraine under a threat of, as they put it, “freezing Europe”. In the process unilaterally breaking existing delivery contracts. There were no Western sanctions targeting Russian gas - it was entirely a political operation initiated by Russian government…
It doesn't make sense that Russia would blow up their own pipeline. They can't blackmail Europe with gas if there's no pipeline to supply the gas. And force majeure? That's pretty far-fetched. Why would Russia care about financial penalties? This is the country that effectively stole over 400 airliners by refusing to return them when the leases were terminated.
