Partisan politics has absolutely nothing to do with this terrible threat.

When Jonathan Schell wrote The Fate of the Earth for The New Yorker,and then a book of the same title in 1982, many were shocked into recognition of what an all-out nuclear war would mean. But with the passage of time, and all the loose talk about nukes and North Korea these days, maybe it is time to revisit a few things, for the forgetful. The need for this recall was especially brought to mind by a report about fancy nuclear shelters being bought by some of the well off; one that would even let six live in it up to a year with no outside help.
