The “president’s finger on the button” meme is wildly off the mark, to use a phrase made infamous by one Hilary’s recently converted supporters, Paul Wolfowitz. (a fact that tells you all you need to know about the Democratic candidate’s foreign policy inclinations.) It is insidiously misleading because the president’s finger is not the one on the button. In fact there is not just one button; there are many, probably some where in the low or middle three digit range. And the fingers that are authorized to press them when called upon to do so are attached to the arms of military officers ranging in rank from O-2 to O-6. That is from First Lieutenant to Colonel in all services except the Navy, where the comparable ranks are Lieutenant Junior Grade to Captain.
