Ms. Bilmes makes an interesting point:
"The Pentagon should be focused on Tactics, not on Deciding our National Purpose."
When Reagan began the spectacle of a President returning Salutes to the Military, it said a lot.
One, the President is a Civilian in charge of, not part of the Military.
Two, a Superior Officer never initiates a salute, only returns it, so, not only does it display a false membership in the Military but, more so, Subservience to it.
