Also, when I questioned the wisdom of putting it somewhere maximally inaccessible, I didn't necessarily mean they should have gone to the opposite extreme of putting it in the middle of a population center.

Nothing personal but this mode of argument seems both fallacious and unhelpful. I suggested an alternative (a somewhat accessible mountain cave) grounded in real-world experience (actual locations of military command centers). I don't understand why you chose to ignore one half of a short comment in order to produce a facile refutation of the other half.
