Nobody has sabotaged European energy security more than European governments. The divestment from nuclear and reliance on LNG was an obvious disaster in the making. Taiwan has made a similar blunder and will pay the price at the next whiff of geopolitical instability.
You've just read how Russia literally sabotaged European energy security and you compared this to... some European countries taking a suboptimal decision?
And Europe is not a single country. My country still happily digs out and burns tons of coal (annoying our neighbors in the process). I hope you're proud of us.
It's not suboptimal, it's a geopolitical disaster that people in 50 years will look back on and ask "how did this happen?"
