Anyone that believes that we will ever be a nuke free world is delusional. That will never happen as long as it remains the most powerful weapon known to man. Even if we do develope something more powerful, nukes will still be a part of many nations arsenals. There is only one way all the world's nukes will be destroyed. It won't be by taking them apart.
I really hope the delegates heard Kissinger's words when he was invited to give his opinion at their meeting...they were wise indeed!!!
