pakistani automic scientist Dr. A.Q.khan is guilty or not?

Answer 1

Technically, no, he is not guilty because he was pardoned. HOWEVER, he did sell nuclear secrets.

In January 2004, he confessed to having been involved in a clandestine international network of nuclear weapons technology proliferation from Pakistan to Libya, Iran and North Korea. On February 5, 2004, the President of Pakistan, General Pervez Musharraf, announced that he had pardoned Dr. Abdul Qadeer Khan. Despite this political scandal he is still regarded as the "Hero of the Nation" by virtually all Pakistanis.

The IAEA reported that Iran had established a large uranium enrichment facility using gas centrifuges based on the "stolen" URENCO designs, which had been obtained "from a foreign intermediary in 1987." The intermediary was not named but many diplomats and analysts pointed to Pakistan and, specifically, to Dr. A.Q. Khan, who was said to have visited Iran in 1986.

The full scope of the Khan network is not fully known. Centrifuge components were apparently manufactured in Malaysia with the aid of South Asian and German middlemen, and used a Dubai computer company as a false front. According to Western sources, Khan had three motivations for his proliferation: 1. a defiance of Western nations and an eagerness to pierce the "clouds of so-called secrecy," 2. an eagerness to give nuclear technology to Muslim nations, and 3. money, acquiring wealth and real estate in his dealings. Much of the technology he sold was second-hand from Pakistan's own nuclear program and involved many of the same logistical connections which he had used to develop the Pakistani bomb.

Answer 2

Of course he's guilty. The man actively exchanged technology with North Korea so Pakistan could build a nuclear weapon. He deserves to be thrown in prison, but of course that will never happen.

Answer 3

He invents cars, right (sorry - couldn't help myself - the typo was just too funny).

Did he not admit that he passed on secrets? That would make him guilty without question.

Answer 4

SOMEHOW YES JUST BY SPREEDING NUCLEAR TECHOLOGY KNOWLEDGE WHERE IT SHOULD NOT BE
