One thing would be that Russia has already set a precedent with a long campaign to attack and destroy civilian infrastructure (power and heat specifically) just before winter to cause bigger humanitarian crisis.
Funny how fickle someone's memory can be. I'm not talking about collateral damage from strikes on military targets, I'm talking about campaign directed against Ukraine's power grid during last autumn and winter.
I even remember people here and on lemmygrad cheering on reports of how much of energy infrastructure was destroyed and admiring pictures of dark cities during blackouts. But I guess that didn't happen? Or maybe the entire thing was fine because it failed?
