Since there's a current HNQ Q&A on the site discussing "state of emergency", I remembered a piece in Tom Clancy's novel "Executive Orders", where the characters discuss validity of certain Presidential actions (specifics don't particularly matter to the question, but they pertained to implementing domestic quarantine via restricting citizen movements to deal with biological weapon attack; which fits the theme of that Q&A).
As a "final" argument to a discussion, one of the characters uttered a very pithy phrase: "The Constitution is not a suicide pact", which kind of settled the discussion in a way. That passage never read well to me, since it seems unlikely that this rationale would fly with SCOTUS.
However, I'm not a constitutional scolar, so I'm not sure if my impression was correct, and as such:
Has SCOTUS ever ruled explicitly based on "The Constitution is not a suicide pact" rationale? (or, alternately, explicitly rejected such a rationale)
