I don't think that anyone seriously fears that the world can be blown to pieces all together. But what one can fear and rightly so are regional things, like in the Middle East, India, Pakistan, the Korean Peninsula, borders in Africa, etc.

Like I said, I'm more worried long term about the environmental issues then the use of arms.
