How do all the pieces fit together?

Okay, so we have mind control, where people are made into sex slaves, assasins, whatever the client wants, then we have the "Alien" conspiracy where they portray aliens in a negative light in the media so that we hate them and consent to an intergalactic war. Then we have the police state idea where they monitor every aspect of human life and invade our privacy in the name of safety. Question is, how do all these things fit together, if they fit at all, or are they independent of each other. There's always a bigger picture, what is it?
