This energy crisis has been consciously in the making.
The US wanted to sell their overly expensive LNG to Europe and has actively created this market. Just read the 2019 US government RAND* report, written years before the 24 February 2022 invasion.

Quote:
"This report concludes that the most attractive U.S. policy options to extend Russia — with the greatest benefits, highest likelihood of success, and least risk — are in the economic domain, featuring a combination of boosting U.S. energy production and sanctions, providing the latter is multilateral.
In contrast, geopolitical measures to bait Russia into overextending itself and ideological measures to undermine the regime's stability carry significant risks."
- to extend = unbend; open to US busness interests.
- attractive U.S. policy = multilateral sanctions
- bait Russia into overextending
The US has followed this script to the letter. Baroness Ursula von der Leyen and her EU in-crowd are enablers, plunging millions of Europeans into poverty.
