There are other plausible places to direct the blame (for the energy issue, not the invasion). I, for one, think this is poor planning and naivete. The cold War wasn't that long ago and tensions have been high for years (since the invasion of Crimea at least). Nuclear energy has been ignored.
Quite the opposite, this was carefully planned. "Never let a good crisis go to waste."
If you like clever-sounding quotes in place of information, the obvious counter is:
"Never attribute to malevolence what is merely due to incompetence." -- Aurthur C. Clark
Intelligence agencies love that quote, since it helps them mask their malevolent actions under disguise of incompetence :)
Fixing the cold house disaster for facing even bigger disaster with global warming?
The world would be better off without Putin, but his successor might be even worse. Ultimately Russia can never be considered a reliable energy supplier for the rest of Europe. Their interests are not aligned. Europeans will have to find other more sustainable and reliable energy sources, as well as cutting heating demand though improved efficiency and insulation.
How are you so confident that this narrative you've adopted is representative of the world as it really is?
Ahahaha. He is the source of all of the evil, right?
