At the meeting, President Ayub Khan downplayed the warnings and swiftly dismissed the offer while believing that Pakistan "was too poor to spend" so much money and ended the meeting saying that, if needed, Pakistan would "somehow buy it off the shelf". After the meeting, Khan met with Bhutto and informed him about meeting with Bhutto later quoting: "''Don't worry. Our turn will come''". Throughout the 1970s and onwards, Khan was very sympathetic to Pakistan Peoples Party's political cause and President Bhutto had spoken highly of his services while promising to ensure federal funding of the national programs of nuclear weapons at the inauguration ceremony of Karachi Nuclear Power Plant– the first milestone towards the goal of making Pakistan a nuclear power on 28 November 1972.In 1978, Khan told them that the design process of the bomb was completed and Bhutto expected the nuclear test in August 1978. Khan then told Murtaza and Benazir that the tests were moved to December 1978, but delayed indefinitely due to political and diplomatic considerations of the country.

In 1975–76, Khan entered into diplomacy with France's Alternative Energies and Atomic Energy Commission (CEA) for acquiring a reprocessing plant for production of reactor-grade plutonium, and a commercial nuclear power plant in Chashma, advising the federal government on key matters regarding the operations of these plants. Negotiations with France over the reprocessing plant was extremely controversial at home with the United States later intervening in the matter between Pakistan and France over fears of nuclear proliferation. Khan's relations with the Bhutto administration often soured because Khan wanted to engage the CEA long enough until PAEC was able to learn to design and construct the plants itself, while Bhutto administration officials wanted the plants based solely on imports from France. In 1973–77, Khan entered in negotiation with CEA for

From the start, studies were concentrated towards feasibility of the plutonium " implosion-type" design, a device known as the

in 1998. Khan, together with Abdul Qadeer, worked on his proposal for viability of " gun-type" designs— a simpler mechanism that only had to work with U²³⁵, but there was a possibility for that weapon's chain reaction to be a " nuclear fizzle", therefore they abandoned gun-type studies in favor of the implosion-type. Khan's advocacy for the plutonium implosion-type design was validated with the test of a plutonium device that was called ''

'' to artificially produce nuclear fission— this nuclear device had the largest yield of all the boosted fission uranium devices. President Zia, despite Khan's political orientation, widely respected Khan for his knowledge and understanding of national security issues when he spoke highly of him during a visit to the Institute of Nuclear Science and Technology in November 1986:

Government work, academia and advocacy

In the 1980s, Khan emblemed in the federal government with a new type of technocratic role, a science adviser, becoming the spokesman of national science policy and advised the federal government to sign an agreement to ensure federal funding from China to commission the Chashma Nuclear Power Plant in 1987. In 1990, Khan advised the Benazir's administration to entered in negotiation with France over construction of nuclear power plant in Chashma. As chairing the PAEC in 1972, Khan played a crucial role in expanding the "''Reactor School''" which was housed in a lecture room located at the Institute of Nuclear Science and Technology in Nilore and had only one faculty member, Dr. Inam-ur-Rehman, who often traveled to the United States to teach engineering at the

Final years

Death and legacy

Starting in 1972, Khan bought an estate in Islamabad and passed away following complications from heart surgery, aged 72, on 22 April 1999. He is survived by his wife, Thera, three children and four grandchildren. When Abdus Salam was ejected from his position in 1974, Khan symbolized of many scientists thinking they could control how other peers would use their research. During the timeline of atomic bomb program, Khan was seen as a symbol of both

. In the 1990s, Khan was increasingly concerned about the potential danger that scientific inventions in nuclear applications could pose to humanity and stressed the difficulty of managing the power of scientific knowledge between scientists and lawmakers in an atmosphere in which the exchange of scientific ideas was hobbled by political concerns. During his time working in atomic bomb program, Khan was obsessed with secrecy and refused to meet with many journalists while he encouraged several scientists working on the classified projects to stay away from televised press and public to due to the sensitivity of their job. As a scientist, Khan is remembered by his peers as brilliant researcher and engaging teacher, the founder of
