I remember having wondered...
...given my utter lack of relevent scientific knowledge, but supposing that a given country DID possess a stockpile of world-ending doomsday machine weapons, IS it safe to drop huge and horrible explosives all over, on, and around said weapons? Maybe factories and processing facilities can be razed to the ground for the Good of All, but isn't a powerful explosion the first step in detonating the contents of an atomic bomb?
Could one reasonably infer that such a device ISN'T present if a sufficiently horrible bombing campaign is being undertaken? Could bombing runs on other lands NOT known to have such incredible weapons accidentally trigger something that our politicians would suddenly have to object to and explain, long and loud, was not our direct doing...kind of like stepping on a mine, except orders of magnitude greater?
