When waging war, the weapons of guilt / shame provide powerful offense.
If you are able to convince a group of people that they are worthless through infiltrating and corrupting their culture so that it becomes materialistic and ugly, stripping out their moral / spiritual values and indoctrinating them with distorted historical accounts so they view their ancestors / race as evil—they will be disarmed. There will be no desire for self-preservation, survival instinct or fighting spirit. They will turn their love to other cultures and peoples rather than their own. They will allow themselves to be defiled, displaced and disowned. They will put up with just about anything. And, it will all be internally justified because they think they deserve it.
You have to give credit to the You Know Whos for actually pulling this off.
However, Yous should be advised that when an oppressed people wake up to the fact that they have been deceived—lied to overtly, lied to through omission, emotionally and intellectually manipulated in the most despicable ways—a special sort of hatred sets in, coupled with an unwavering will to succeed and unstoppable desire for vengeance. Like a tightly coiled titanium spring, there is a huge amount of potential energy and force that is released when the pressure of phony guilt and shame have been removed.
