Here's a trial balloon that deserves not only to be shot down, but shredded, dispersed, and probably exorcized:Pentagon wants 'mini-nukes' to fight terrorists. Imagine what happens when other nations build these and then they fall into the wrong hands. (Due to the nature of their likely uses, tactical weapons tend to be more dispersed and less well guarded than strategic ones.)
And, oh yes, might there be a moral issue about a national policy of envisioning and thus encouraging (in the sense of failing to maintain our stand against) the casual use of nukes? Or maybe a strategic cost to those of us living in a target-rich environment about undermining the international norm against the use of nuclear weaponry? Hello?
