Almost all of the governments have agreed that they will not acquire nuclear weapons and that they will allow the International Atomic Energy Agency to monitor their commercial and research nuclear power operations to ensure that nuclear materials - highly enriched uranium and plutonium - are not diverted to use in weapons.

Especially in the case of India and Pakistan, it's very clear that significant parts of the elites in both countries view having nuclear weapons as a ticket to prestige.

There is an international treaty framework for this. It's the Nuclear Non-Proliferation Treaty (NPT). Most countries in the world are members of the treaty.

I still find each day too short.

So the idea about how detonation of a nuclear weapon might happen vary, you know - some people are especially concerned about terrorists getting their hands on nuclear weapons and using them. Some people are worried that there might be a nuclear war between India and Pakistan. Some think the Middle East, were Israel already has nuclear weapons and where other countries may be interested at some point and acquiring them, might be a flash point.

We've been in a period of relative stability and cooperation since the end of the Cold War among the world's major powers, but that may not always exist. And certainly one could even predict that there will be periods of hostility or tension ahead.

For anything worth having one must pay the price; and the price is always work, patience, love, self-sacrifice - no paper currency, no promises to pay, but the gold of real service.
