"And I'm grateful for your advice and assistance. I respect you as a professional, Lieutenant; however, I will give you this warning with confidence."
To know something is to be clad in preconceived notions. It's fundamentally the same issue the army faces as an organization that relies too heavily on preconceptions of what is supposedly common sense. As a sensible person herself, Tanya can sympathize with Serebryakov's misunderstanding.
It's true that if you're familiar with the Commie ideology, it's hard to think that they would simply release people from the lageri. But they can sure do it anyway.
"Don't get caught up in the Communists' official position. They can talk out of three sides of their mouths. If they find something that lets them infuriate people, they'll be as diligent about it as religious fanatics." Tanya practically spits the words out in exasperation.
"Forget principles. These Commies are driven more by their needs in the moment than their ideology. Authoritarians in the guise of revolutionaries have always used this trick-it's no surprise."
Commies, Commies, Commies. You could call them an awful societal reaction. So what's so formidable about them? Tanya Knows well. She can't help but understand.
"These bastards steal causes for their own ends. Expect the worst."
