== Career in Europe == In 1972, Khan joined the Physics Dynamics Research Laboratory (or in Dutch: FDO), an engineering firm subsidiary of Verenigde Machinefabrieken (VMF) based in Amsterdam, from Brabers's recommendation. The FDO was a subcontractor for Ultra-Centrifuge Nederland of the British-German-Dutch uranium enrichment consortium, URENCO Group, which was operating an uranium enrichment plant in Almelo, and employed gaseous centrifuge method to assure a supply of nuclear fuel for nuclear power plants in the Netherlands. Soon after, Khan left FDO, but was consequently offered a senior technical position by URENCO, initially conducting studies on uranium metallurgy. Uranium enrichment is an extremely difficult process because uranium in its natural state is composed of just 0.71% of uranium-235 (U235), which is a fissile material, 99.3% of uranium-238 (U238), which is non-fissile, and 0.0055% of uranium-234 (U234), a daughter product which is also a non-fissile. The URENCO Group utilised the Zippe-type of centrifugal method to electromagnetically separate the isotopes U234, U235, and U238 from sublimed raw uranium by rotating the uranium hexafluoride (UF6) gas at up to ~100,000 revolutions per minute (rpm). Khan, whose work was based on physical metallurgy of the uranium metal, eventually dedicated his investigations to improving the efficiency of the centrifuges by 1973–74. Frits Veerman, Khan's colleague at FDO, uncovered nuclear espionage at Almelo where Khan had stolen designs of the centrifuges from URENCO for the nuclear weapons programme of Pakistan. Veerman became aware of the espionage when Khan had taken classified URENCO documents home to be copied and translated by his Dutch-speaking wife and had asked Veerman to photograph some of them. In 1975, Khan was transferred to a less sensitive section when URENCO became suspicious and he subsequently returned to Pakistan with his wife and two daughters. Khan was sentenced in absentia to four years in prison in 1983 by the Netherlands for espionage, but the conviction was later overturned due to a legal technicality. Ruud Lubbers, Prime Minister of the Netherlands at the time, later said that the General Intelligence and Security Service (BVD) was aware of Khan's espionage activities, but he was allowed to continue due to pressure from the CIA; with the US backing Pakistan during the Cold War. This was also highlighted when despite Archie Pervez (Khan's associate for nuclear procurement in the US) being convicted in 1988, no action was taken against Khan or his proliferation network by the US government which needed the support of Pakistan during the Soviet–Afghan War. Henk Slebos, a Dutch engineer and businessman, who had studied metallurgy with Khan at the Delft University of Technology, continued providing goods needed for enriching uranium to Khan in Pakistan through his company Slebos Research. Slebos was sentenced in 1985 to one year in prison, but the sentence was reduced on appeal in 1986 to six months of probation and a fine of 20,000 guilders. Though Slebos continued to export goods to Pakistan, and was again sentenced to one year in prison and a fine of around €100,000 was imposed on his company. Ernst Piffl was convicted and sentenced to three and a half years in prison by Germany in 1998 for supplying nuclear centrifuge parts through his company Team GmbH to Khan's Khan Research Laboratories in Kahuta. Asher Karni, a Hungarian-South African businessman, was sentenced to three years in prison in the US for the sale of restricted nuclear equipment to Pakistan through Humayun Khan (an associate of Khan) and his Pakland PME Corporation.

=== Smiling Buddha and initiation ===
Upon learning of India's surprise nuclear test, 'Smiling Buddha', in May 1974, Khan wanted to contribute to efforts to build an atomic bomb and met with officials at the Pakistani Embassy in The Hague, who dissuaded him by saying it was "hard to find" a job in PAEC as a "metallurgist". In August 1974, Khan wrote a letter which went unnoticed, but he directed another letter through the Pakistani ambassador to the Prime Minister's Secretariat in September 1974. Unbeknownst to Khan, his nation's scientists were already working towards feasibility of the atomic bomb under a secretive crash weapons program since 20 January 1972 that was being directed by Munir Ahmad Khan, a reactor physicist, which calls into question of his "father-of" claim. After reading his letter, Prime Minister Zulfikar Ali Bhutto had his military secretary run a security check on Khan, who was unknown at that time, for verification and asked PAEC to dispatch a team under Sultan Bashiruddin Mahmood that met Khan at his family home in Almelo and forwarded Bhutto's letter which instructed Qadeer Khan to meet the Prime Minister in Islamabad. Upon arriving in December 1974, Khan took a taxi straight to the Prime Minister's Secretariat. He met with Prime Minister Bhutto in the presence of Ghulam Ishaq Khan, Agha Shahi, and Mubashir Hassan where he explained the significance of highly enriched uranium, with the meeting ending with Bhutto's remark: "He seems to make sense." The next day, Khan met with Munir Ahmad and other senior scientists where he focused the discussion on production of highly enriched uranium (HEU), against weapon-grade plutonium, and explained to Bhutto why he thought the idea of "plutonium" would not work. Later, Khan was advised by several officials in the Bhutto administration to remain in the Netherlands to learn more about centrifuge technology but continue to provide consultation on the Project-706 enrichment program led by Mahmood. By December 1975, Khan was given a transfer to a less sensitive section when URENCO became suspicious of his indiscreet open sessions with Mahmood to instruct him on centrifuge technology. Khan began to fear for his safety in the Netherlands, ultimately insisting on returning home.
