If I want to tax advice I go to an accountant.
If I want advice on working out I go to a trainer.
If I want to know how to fly a plane I'll talk to a pilot.
If I want advice on National Security I'll talk to people who (like these 26) have worked in the field.
Ah, but you don't want advice on national security. You want to judge the existing policy.
Here is a better analogy:
If I want to know how my food tastes, I don't ask a cook.
If I want to know if my house was painted the best color, I don't ask a painter.
If I want to know if that music sounds great, I don't ask a guitarist.
I ask myself.
