You're 100% right about moronic energy policies pushed by Germany up until 2021 but EU, if anything, played a positive role here - it was EU and Member States other than Germany that since 2015 had been pushing the EU energy diversification directive which at the end of the day prevented much larger disaster when Russians executed their blackmail in 2021. The battle to save nuclear power was also a complex game of interests where EU played a positive role by providing the scientific assessment (JRC etc) to counter the hysterical arguments from German "greens" and gas industry. Trump routinely blames "EU" for continuing to purchase Russian gas and oil four years into the war, but there's nothing further from truth - it's not "EU", it's a small group of Member States which do so exclusively because energy policies is one of many competences that are explicitly excluded from EU subsidiarity which means these countries are free to do so until they agree to stop these purchases voluntarily - which should happen from 1 January 2027.
