I am skeptical whenever anyone claims there is a single super-secret super-villain super-plan, or when Trump is considered a disruptive outsider. Trump has a long association with politics, including the Clintons, and would have received the Ron Paul treatment had he been a real threat.
I suspect there are people who want the kind of global power associated with various shadow government theories, and I would not be at all surprised to learn that there are people in the background holding the real reins of power, but I doubts such people form a cohesive global secret cabal.
