No..it not possible.Is that even possible... to have a nuclear-free world? And even if it was, why is it America's right to assert rules banning atom bombs on other soverign nations when America herself has nukes.
...but saying it would be nice is easy politics for virtually any politician on the planet. McCain knows nukes aren't going anywhere.
If Obama starts trying to unilaterally monkey with the US nuclear stockpile McCain will be right there to say No.
IMO while a nuclear world in some future may/likely will have a major power war with nukes..a non-nuclear would have had a few more then 2 WW's by now.
America has the same -right- as any other nation state on this planet to assert its views.
-right- is only applicable if you assume that international law is actually some legal binding thing and not simply a written down set of beliefs applied during a particular time in History.
Now if you do take International Law to be deified as THE LAW Judge Dredd style...this is a United Nations Banning.
The USA is asserting the very standard that gives the USA the so called right to say "you can't have nukes"
He who has the most "______" wins.
That is the only rule on this dog eat dog planet.
You lose the game of nation states you lose hard....lotta ruins around to remind people of the costs of the overall game.
