Re: Pakistan test-fires new nuclear-capable missile
That depends who you target. The world has only ever seen startegic nuclear weapons used in way, which target entire cities.
No one has ever used a tactical nuclear device in war. It is entirely possible to use on on a battlefield. For example, it is unlikely that civilians would be living in the vicinity of an artillery battalion positioned at an active front line. In such a case, a short-range tactical device could be used to eliminate the battery with more certaincy than a conventional strike, and still be 99% sure of not causing civilian casualties.
