>As countries get more sophisticated in terms of industry, electronics etc the effort to create a nuclear weapon gets more achievable. Keeping the rest of the world at a primitive level where thats not achievable isn't an option. So we may as well work out what the world is going to be like with a whole lot more countries having nuclear weapons becuase thats the future.

OTOH, we all know how Iraq was rewarded for NOT having achieved nucular independence.
