He was loved by our nation( because) of his critical contribution in making us a nuclear weapon state. This has provided us security against an aggressive much larger nuclear neighbor. For the people of Pakistan he was a national icon.

Abdul Qadeer Khan

Abdul Qadeer Khan ( (listen); Urdu: ??? ?????? ????; 1 April 1936 – 10 October 2021) NI, HI, FPAS, DEng, known as A. Q. Khan, was a Pakistani nuclear physicist and metallurgical engineer who is colloquially known as the "father of Pakistan's atomic weapons program". An émigré from India who migrated to Pakistan in 1952, Khan was educated in the metallurgical engineering departments of Western European technical universities where he pioneered studies in phase transitions of metallic alloys, uranium metallurgy, and isotope separation based on gas centrifuges. After learning of India's 'Smiling Buddha' nuclear test in 1974, Khan joined his nation's clandestine efforts to develop atomic weapons when he founded the Khan Research Laboratories (KRL) in 1976 and was both its chief scientist and director for many years. In January 2004, Khan was subjected to a debriefing by the Musharraf administration over evidence of nuclear proliferation handed to them by the Bush administration of the United States. Khan admitted his role in running the proliferation network – only to retract his statements in later years when he leveled accusations at the former administration of Pakistan's Prime Minister Benazir Bhutto in 1990, and also directed allegations at President Musharraf over the controversy in 2008.Khan was accused of selling nuclear secrets illegally and was put under house arrest in 2004, when he confessed to the charges and was pardoned by then President Pervez Musharraf. After years of house arrest, Khan successfully filed a lawsuit against the Federal Government of Pakistan at the Islamabad High Court whose verdict declared his debriefing unconstitutional and freed him on 6 February 2009. The United States reacted negatively to the verdict and the Obama administration issued an official statement warning that Khan still remained a "serious proliferation risk". On 10 October 2021, Khan died of COVID-19 complications.
