I may be many things, but I doubt "brainwashed" is one of them. On the other hand, how would I know? You think you've seen through Bucha. We won't know until the war is over.
My thought on Putin are far from simple. I've written many articles on Medium about him and his regime. I'm not here to denigrate Russians.
Okay, let's say you're right. What is Putin's end game here? How do Russians prosper going forward? There are no checks and balances, as there are in the west. It's just his opinion and few others around him. He's gone mad and there's no way to fix it so many Russians pretend not to see it. Again, explain how this all works out for Russia. I'd love to know.
