on 5 August 2016 Foreign Policy magazine published an article about that very subject with a subhead that openly proclaimed it:
, the article focused on the "timeline" of nuclear events based on an anecdote from 1979:
All those steps leave something like eight minutes from the first call to the White House to the last moment at which the president can act.
Much of those eight minutes is lost to the task of informing the president. The first call to the White House isn’t to the president, of course. It is to a person designated by the president for this task. (Well, probably the military assistant to that person — another minute ticks off the clock.) In November 1979, that person was Zbigniew Brzezinski — then-President Jimmy Carter’s national security advisor and father to Mika, who was sitting next to Scarborough, solemnly shaking her head at the idea of Trump with the bomb.
You should really watch Zbig tell the story, though the bottom line is that he recalled having only three minutes to decide whether or not to inform the president, after which the president had four minutes to decide whether or not to retaliate. At the end of his three minutes, Brzezinski’s military assistant called back to tell him it was a false alarm — someone had left a training tape running. Brzezinski went back to bed. He never woke his wife, by the way. He decided that if it was a Soviet nuclear attack, it was better to let her die in her sleep.
Among the people weighing in after the debate were who were able to assess the rumor and rate it was nuclear security expert Joe Cirincione, who issued two tweets about the controversy — one explicitly stating that Clinton did not disclose classified information and another reiterating that the information was already widely known and often cited:
No, @HillaryClinton did not reveal any secret about how quickly we can launch . This is widely known, often cited. unidir.org/files/publicat …
