I propose that the greatest trick these devils ever pulled was convincing the world they were more powerful than they actually are. It's a very good trick!

I am not so sure about that line of thinking. It is literally the worst thing you can do is to underestimate your enemy.

But then again, yes, people do have more power than they realize, so one of the goals of the propaganda machine is to make people feel powerless.

But this doesn't mean that they can just underestimate the will and the power of the tyrants either.
