The latest information I have had from the followers of Bush is that he has demanded and received permission to use nuclear “bunker busters” in Iran in a preemptive strike. As a nuclear veteran (Operation Redwing, Bikini, 1956) I can affirm that this is absolute madness. The “bunker buster” is a cute sounding name for a nuclear horror. Air bursts are horrible enough, doing incredible destruction through heat, shock and high initial radiation. The fallout from an air burst is registered around the world. A surface or subsurface burst is even deadlier and more long lasting.
