All the world knows that Dr. A. Q. Khan (Khan) stole but incomplete diagrams & he initailly thoughts he can make bomb with few technicians but this was his Deputy Dr. G. D. Alam (Dr. Alam) who told him that you can't do this without proper manpower.
Dr. Alam is the actual man behind this achivement for Pakistan and he is the man who achived this for Pakistan (Dr. Alam died on 5th December 2000). (This is Dr. Alam once said that "History don't lie" this is true.
This is the book 1st time mentioned Dr. Alam as his deputy, which means his investigation and research is very thorough, Dr Alam is the man who negotiated with all seller throughout the world for Pakistan's bomb, but refuse to help Dr. Khan sell the technology for personal gain)

I found it a fascinating of how one man could become a major dealer in nuclear technology.

The lax security in the European nuclear program allowed a Pakistani engineer Khan to steal the centrifuge designs. Khan took those designs to Pakistan to help create a nuclear bomb there. Soon Khan became the head of a major nuclear organization in Pakistan. Soon the Pakistani had developed centrifuges technology that could bypass the international controls on making nuclear bombs.

Here contrary to the writer, I am not so sure from his evidence the US atomic program for peace failed as he suggested. The appeal of Khan technology to rogue countries was they could bypass the checks here. So Khan sold this technology for large sums to Iran, Libya, North Korea and maybe one more.

Part of the problem stopping Khan was finding what was happening. Then it was his prestige in Pakistan. Plus the free world's need for Pakistani support both in the cold war and the war in Afghanistan after 911 but eventually in January 2004, under world pressure Khan was arrested and put under house arrest. So finally stopping Khan, leaving us with a problem of knowing how much damage Khan did!

Now it is a few years since the book was written. Iran is still trying to make a bomb. At best, Khan would have given it a boost. The Libyan spent much money for nothing and eventually gave up on nuclear bombs, so his contribution there was useless. North Korea appears according to recent information gave up earlier on this type of uranium enrichment technology and went back to the power reactor method. Maybe he helped with the bomb design. The last unknown country, I cannot comment.

Finally I am left wondering what happened to the money the Pakistani got from these countries? Khan lived a good life but he did not take much of the money. I suspect that it went to the Pakistan's nuclear program which I find a disturbing conclusion.

Overall if you are interested in this, you will find this a fascinating read.
