PositiveThe New York Times Book ReviewFor those who have not read other recent books on nuclear dangers, Ellsberg provides valuable reminders of stubborn realities. By employing personal stories from his time in the 1950s and 1960s working alongside Kahn and other ‘wizards of Armageddon’ at the RAND Corporation and as a consultant at the Pentagon, he makes hard-to-believe truths more credible … Ellsberg’s effort to make vivid the genuine madness of the ‘doomsday machine,’ and the foolishness of betting our survival on mutually assured destruction, is both commendable and important. And his inability to describe a feasible way to eliminate nuclear dangers does not distinguish him from scores of others who have also been trying to rethink the unthinkable.
