Yet you offer nothing to back up your claims that the goal of the CFR is "to weaken national sovereignty and push towards the establishment of a North American superstate." Instead, you say "I came away with the distinct impression that what they stand for is exactly what I stated before." Give some specifics of what gave you that impression? You have already questioned why a very broad cross section of some of the most accomplished experts on United States foreign affairs would retain their membership in such an organization. You simply haven't offered any evidence to support the CFR is what you say it is, and among the best evidence to say it isn't is that it retains the members it does.
Why don't you show us where the CFR upholds the sovereignty of the United States and the authority of the US citizen to direct their government and government policy as opposed to an NGO like the CFR and their "task forces"?
