Yes...he ignored a ton of intel that countered his stupid ideas. The US, Brits, Swedes...everyone told Stalin what was coming. Even his own intel people. They captured German soldiers who also told them what was going on. A very amazing part of history!
I have some theories, I think Stalin deep down didn’t mind the population reduction. It gave him more leverage in negotiating after the war, because, after all “We lost 20 million people”.
Also, Stalin didn’t shed a tear over Hitler getting rid of a lot of Jews for him.
Hitler told Stalin, too, in his rambling “Mein Kampf”. Hitler told the entire world again and again what he intended to do. And then did it.
Liberals do the same today. They constantly state their intentions to destroy all non-liberals. They talk about using camps and death squads. These are people in the RAT party apparatus. The RAT party leadership says it over and over, just not as out front. Yet the stupid RINOs just don’t listen. The fools think they can work a deal. They can’t. The RATs intend to utterly and mercilessly destroy all opposition. Forever.
