I don’t think that nuclear warfare can ever really be justified, because I really don’t see how you can justify putting many millions of people to their death, and many others to horrible diseases, and a nuclear winter. I don’t see how you justifiably take a part of the world effectively off the map, for any reason, no matter whether its to end a long, hard war, even if you are the ‘goodies’, and by dropping a nuclear bomb on the ‘baddies’, although you will probably kill millions of them, you will save thousands of your people, no matter if the situation is like it is at the moment between the Americans and the Afghans, and if the Americans did drop a nuclear bomb it would be a case of the ‘goodies’ getting revenge on the ‘baddies’ rather than doing it to save a lot of lives, they’d be doing it for revenge, even though it was probably only a select group of people, and I really don’t see how this can be justified, another thing is that in most situations people see themselves as the goodies, and the reason its happening is because the other people started it. An old phrase comes to mind ‘it all started when he hit me back.’
I think that the question is not can nuclear warfare ever be justified, but can you justify going up and killing millions of mainly innocent people in any situation, no matter how severe it is, what the circumstances are, and what they did to you, I think that the answer to this question would have to be no, because in the ten commandments, it says ‘thou shalt not kill, and in dropping a nuclear bomb, you’re blatantly ignoring one of the ten commandments.
I think that in the case of nuclear weapons, the just war theory should really be scrapped, because people will think they’re fighting for a just cause, when in all truth dropping a nuclear bomb can never be just. In this sort of business (nuclear weapons) there can really be no one who are from competent and legal authority who can control these ‘animals’ dropping nuclear weapons on other parts of the world, and they probably wouldn’t live through a nuclear war, because almost all of the world as we know it would be finished.
In conclusion, I don’t think that any nuclear war can ever really be justified in any way.
