Retired diplomat Jamsheed Marker talks about “meeting characters, genuine and shady, in tiny cafes tucked away in obscure villages deep in the beautiful Swiss and German countryside”.

One of Pakistan’s best-known diplomats has given an unprecedented account of how his country clandestinely built its nuclear arsenal using its diplomatic network in Europe.

In Cover Point: Impressions of Leadership in Pakistan, an autobiographical account of Pakistan’s politicians, retired diplomat Jamsheed Marker, 94, says: “This exercise involved a bit of James Bond stuff, and I remember Ikram and myself meeting characters, genuine and shady, in tiny cafes tucked away in obscure villages deep in the beautiful Swiss and German countryside.”

Mr. Marker served as Pakistan’s Ambassador to the Federal Republic of Germany between 1980 and 1982, when the meetings took place, which led to Pakistan acquiring sensitive technology from European firms for its nuclear weapons programme.

“The Embassy had a Procurement Department [the nomenclature really fooled nobody] headed by a most able officer of Minister rank named Ikram Khan, who was seconded from our nuclear establishment headed by Dr A.Q. Khan. Ikram was a superb officer, knowledgeable, low-key and efficient, and went about his sensitive job with the combination of initiative and discretion that were its primary requirements,” writes Mr. Marker , revealing how Pakistan sourced technology for its nuclear programme from western markets.

Mr. Marker’s disclosure sheds light on a wide array of willing partners from among firms in Europe which were willing to partner Pakistan’s quest for nuclear weapons, for a price. Mr. Marker, who worked directly under the supervision of General Zia-ul-Haq, played a peripheral role as the “Procurement Department” operated under a cloak of secrecy.

Mr. Marker, served for three decades in various important embassies of Pakistan, but reached the most successful phase of his career with his back-to-back appointments as Pakistani Ambassador to Bonn, Paris and Washington DC during the tenure of Gen Zia (1977-1988). Mr. Marker said that he admired the way Gen Zia (who became civilian President in 1985) diverted the West’s attention while going all out for giving Pakistan its nuclear weapon. “I maintain a mild, amused contempt for the enthusiasm with which western industrial enterprises, in their pecuniary pursuits, conspired with us to evade their own governments’ law prohibiting all nuclear transfers to Pakistan,” he writes in what is the first account from one of Gen. Zia’s key diplomats on the modus operandi adopted to build the nuclear bomb in Pakistan.

Mr. Marker says the U.S. spy services were aware of Pakistan’s determination to go nuclear and were unable to prevent Gen. Zia.
