There is ANOTHER smaller, parasitic COUNTRY inside of the USA, which secretly RULES us.
The ISIS concept force us to consider that there are non-country actors in the world which function a lot like states.
Blackwater did something similar —near armies can be raised privately.
We already were familiar with military/political occupation of the FORMAL variety.
This new Deep State concept is also new: SECRET OCCUPATION. The concept seems silly or ridiculous, but that may be what we have in the here and now.
There seems to be some entity ABOVE the US President; they have their own personel, funding, norms and customs.
