Its more humane to blow folks to smithereens then to incinerate them.

Its like that silliness of Jimmy Carter over the neutron bomb. Its okay to annhilate a city and kill all the people but it is wrong to just kill all the people.

Or its okay to drop 155mm artillery on houses when you don't know who is inside but if you kill a wounded perp with a bullet to the head, you're a criminal.

This all makes perfect sense to me.
