The US administration in 1982 was deeply concerned over Pakistan's clandestine nuclear programme and possibility of it leaking nuclear components to other countries but President Zia-ul-Haq dismissed such apprehension and conveyed that India was behind such "insidious" campaign to defame Islamabad, as per declassified CIA documents.
In a letter to the then President Ronald Reagan, Zia said Pakistan neither possesses nor has transmitted any designs or specifications of nuclear components to anyone and that it is unthinkable for the country to become instrumental in the spread of atomic weapons.
He also assured the American President that Islamabad would not build a nuclear bomb, asserting its atomic programme was for peaceful purpose.
In the confidential letter dated July 5, 1982, recently declassified by the CIA, Zia had made a veiled reference to India and said there were "open and insidious" attempts to weaken Pakistan's ties with the US and that the peaceful nuclear programme has been misrepresented to divert attention from critical developments in the region.
Zia also took strong objection to assertion by the then US Envoy Vernon Walters that there were "incontrovertible" information that Pakistan was planning to acquire nuclear weapons. PTI
