Theories.......

Man's interpretation of life, etc, is his own belief verbalized as a theory.  

You put up a lot of links to theories  

Just like electromagnetic radiation manifest itself differently so too do world events. Jog sees conspiracy at every turn like night vision goggles see infrared, but there's other spectrums out there you turn a blind eye to. I guess we all put on whatever filter we want to in order to discern the  truth that makes sense for us based on our understanding of the world.

Sure, people, nations, conspiracy to affect events on occasion, but mostly people and nations act selfishly to protect themselves. They work with one another as long as it's within their own interest to do so. Alpha males don't play well with one another so the idea hundreds of influential people get together and manipulate events by sticking to Rube Goldberg type master plans is not credible.

Mitch McConnell and Paul Ryan pledging support to Democrats in order to thwart Donald Trump is not part of a master plan; it's power happy politicians trying to maintain their positions.
