That's pretty restrictive. I know a large number of scientists and computer programmers who believe the only thing you can trust are protocols and math, and they're usually completely unable to function outside of the narrow domain of their work.
I think a better philosophy is to trust that people will behave according to the incentives and information available to them. So if there is an organization out there, you can bet that it will act to expand the scope of the organizations' actions, because organizations that don't do this eventually get replaced by ones that do. If the organization is tasked with keeping tabs on all of America's adversaries, you can bet that they will see adversaries wherever possible to preserve a purpose for the organization.
