Okay, so North Korea has the bomb and Iran is working on one - or so we're told. The International Atomic Energy Agency reckons places like Taiwan, South Korea and Japan could have one in short order - if they really want one. Indonesia is considering developing nuclear power and, suprise, so is Australia. I wonder if that's connected.

And then there's Egypt and Turkey and ...

I can't help thinking that the more countries that have them the more pressure will build on those that don't to get them. Has the horse already bolted?
