North Korea is a shambles of a country with a deceased economy and a population of a paltry 23 million mostly starving people. It could be neutralised by the Essex ladies' netball team.

Want to be listened to ? Rule n°1 never say things twice. Isotopic enrichment was prone to become accessible anytime soon as centrifugation became easier . Nukes were tinkered 70 years ago by few. They are accessible now. The mistake was to keep them so important.

When Pakistan detonated its first device, it was alleged, in an effort to belittle the Pakistani Scientists' work, that even a graduate student could assemble such a device. Now we are talking about some dangerous blue-prints of sophisticated devices. Is it because an Arab is heading the IAEA?

Nuclear blindness: the mistaken belief that the bigger the bang the more powerful the weapon. A biobomb using a highly contagious virus would spread through the population at a geometric rate. The genomic revolution enables construction of supervirus by rogue regimes-focusing on nuclear is naive.

Dr. A.Q.Khan recently told Hamid Mir in a phone interview aired on GEO TV in Islamabad that the real proliferators were European companies, which wanted to make money on selling nuclear technology to anybody that could pay the best price. What about that?

Why is it ok for the US - the most aggressive nation - to have Nuclear weapons but not others. They fear attack from the US for ignoring, quite rightly, the US Governements policy demands. No one should have Nuclear weapons. Not teh US or GB or France or anyone. Iw will only end in tears!

Pressure must be put on Pakistan to hand over AQ Khan or at least have him interrogated by Western intelligence agencies. His activities have resulted in a mortal threat to us all. This issue transcends any niceties of hitherto accepted diplomacy

Nuclear arms race will only stop when the rest of the world is covinced that the holders of nuclear arsenal agree genuinely for disarmament. It is immoral to shout for control of the nuclear armament in non nuclear countries whilst arming themselves to the hilt.

Some people will nver get it until its too late. They are waiting for the definitive mushroom cloud. If Libya is known to have been receiving this information, it is a better than safe bet that others also got the information.

They should have posted it on the Net - I'd quite like my own set of plans for a nuclear bomb. Come in handy as a deterrent where I live.

I have no confidence in the US and the coalition's claims. They could simply be fibbing as they did in the case of Iraq.

Theirs claims must be not only double checked, but triplenad and quadruple checked! What bewilders me is IAEA's lost authority. The world ordre needs re-organization.

u can'tprove Israel has nukes but it is widely reported that they do.

Only if you can confirm and have proof that they HAVE bought the blueprint as a fact, do you have real news, other wise this article is just speculative sensation!
