A second Moon program could not hope to elicit the same combination of fear, funding reduction immunity and pure profiteering (shielded by 'national security' and state secrets).
NASA needs to dedicate its pittance of a budget to another manned Moon mission right now about as much as I need another person to point out to me just how much money our government likes to spend on military boondoggles.
But it appears the NSA even has their own secret space program http://en.wikipedia.org/wiki/Blackstar_(spacecraft)
