Not the tactical nukes but the one that can destroy an entire town or city. If their sole purpose is to inflict economic, political, and social harm on civilians, shouldn't they be illegal? I ask because I recently found a copy of some documents by General Curtis Lemay which he admitted that, had America lost, he would have been brought up on war crime charges for the approval of nuking Hiroshima and Nagasaki. I'm well aware of the victor punishing the loser but would there be an abstract, legal basis for such a charge?
