One of the key tasks of imperialist propaganda is to dis-empower the ordinary citizen. The product of this system is the myth of the powerful to whom one goes to make requests and to seek favors, and before whose power the average citizen is completely powerless. All action must be funneled through official channels, for the imperialist elite have that extra asset known as ‘power', which is an abstraction but nevertheless quite real in that elites have it and you do not. This is a myth, but it is a persistent myth. As one example of this sort of thing, I keep agitating to get a people's movement started to end the Iraq War, ignoring Washington, and just getting the job done ourselves. Such a concept would be quite alien to the average citizen of the Imperial Empire, as I have found out in the past, when the suggestion was met with a flurry of raspberries. Apparently the average citizen is so brainwashed they do not understand that they have the power to say to an empire, ‘Collapse', and its falls immediately into ruins at their feet, as we have seen for ourselves. You just say no. Your soldiers just say no. Its just that simple. You can tell that imperialist mythology has reduced the population to infantilism when such concepts are regarded as incomprehensibly alien.
It is important that a wolf only be seen dressed up in sheep's clothing, which is the foundational principle of all propaganda. How can one do evil, as imperialism requires, while appearing to be good. For this reason the use of brute force must be saved as a last resort, or effective propaganda must be manufactured to justify the use of murder as a tool to control dissent, for to do otherwise would to run the risk of losing that all important sheep's skin, exposing the wolf.
Hitler understood this essential truth about propaganda, and while there are many ways to deceive and thus many methods of doing propaganda, Hitler insisted that since the people are like good sheep, and they do not believe that wolves exist, if you are going to tell them a lie you should tell them a Big Lie, for trusting sheep that they are, they believe that the imperialist wolves are sheep just like they are, and thus could not tell such lies, and therefore they will believe the Big Lie. However they do tell small lies from time to time themselves, and thus it is dangerous to tell them small lies, since they might suspect something is amiss, so therefore the safest strategy is to throw off all restraint and tell them Great Big Lies instead, for as Hitler pointed out, that technique works every time.
