Secretary of Defense Harold Brown to Ambassador-at-Large Gerard C. Smith, enclosing excerpts from memoranda of conversations with Geng Biao and Deng Xiaoping.

U.S. State Department cable states that the Carter administration has “reached a dead end” in its efforts to curb the proliferation of nuclear technology in South Asia. The State Department is wary of taking too strong an approach to Pakistan’s nuclear endeavors, given the security ties between the two countries and concerns about Pakistan’s stability.

Anthony Lake, director of the Policy Planning Staff, writes to Secretary of State Cyrus Vance about available options to deter Pakistan’s further proliferation while still maintaining “good relations.” Lake suggests exploring the idea of pressuring groups and countries providing aid to Pakistan, and wonders whether the sale of F-16 fighter-jets could sway Pakistan’s military to scale back their nuclear effort.

A State Department Bureau of Intelligence and Research report on the desire of the Pakistani leadership to improve relations with the U.S. and negotiate a more substantial aid package. The report warns against becoming too close to General Zia, as close relations with him “might harm future relations” should he be swept from power.

Just a few months into President Reagan’s first term his administration wanted to make its own mark on nonproliferation policy. The report suggests building “broader bilateral relationship[s]” and offering political and security incentives could persuade states considering developing nuclear weapons to cease these efforts.

Memorandum from the Arms Control and Disarmament Agency suggests that the prospects for dissuading a Pakistani nuclear test were dimming and suggests possible U.S. responses should detonate a device.

A U.S. Department of State Bureau of Intelligence and Research report offers an overview of the Indian and Pakistani nuclear programs, and speculates how the development of a weapon in one country could strain relations with Washington and lead to a regional nuclear arms race. India is less likely to take preventive action against Pakistan because of the risk of “antagonizing China,” the report suggests.

In response to an IAEA report that Pakistan diverted plutonium from the Karachi nuclear power plant, a CIA analysis suggests that the Pakistanis “were not overly concerned” about these events. Of greater concern to regional security and stability was the discussions of the sale of F-16 fighter-bombers as part of a U.S. aid package to ensure Pakistan’s cooperation in the covert efforts against Soviet troops in Afghanistan.

Special National Security Estimate 31-32/81 outlines possible Indian preventative action that could be taken against Pakistan’s nuclear program, and possible responses should Pakistan develop a weapon.

Secretary of State Haig writes to Senator Mark Hatfield (R-OR) to explain possible U.S. courses of action with regards to military and economic aid should Pakistan test a nuclear weapon. A test, Haig said, would “in all probability” lead to an end of economic and military support.

A planned update of the Special National Intelligence Estimate 31-32/81 concluded that Pakistan’s nuclear program was continuing and new evidence suggested a “significant” Chinese role in the design of the weapons. Despite this new evidence, CIA estimates suggest that the required amount of fissile material for weapons production would not be available as early as had been predicted, and that a Pakistani nuclear test was not imminent.

A summary of U.S. State Department cable traffic regarding Pakistan’s nuclear efforts in 1981-1982. While the Reagan administration was inclined to give Pakistan some leeway in light of their support for anti-Soviet forces in Afghanistan, the acquisition of sensitive nuclear technology from abroad was still something that the administration was against. Evidence that Pakistan had made efforts, some successful, to acquire specific technology that suggested a nuclear test was being prepared raised a red flag in the U.S. government

A report to the State Department from Ambassador General Vernon Walters on his meeting with President Zia, where he confronted the Pakistani President with “incontrovertible evidence” that his country had “transferred designs and specifications for nuclear weapons components to purchasing agents in several countries for the purpose of having these nuclear weapons components fabricated for Pakistan” despite promises not to do so. Zia denied the charge, and Walter later commented, “either he really does not know or is the most superb and patriotic liar I have ever met.”

After Ambassador General Vernon Walters’ second day meeting with President Zia, the Pakistani leader verbally acknowledged U.S. evidence that Pakistan sought nuclear weapons components from abroad despite promises not to do so. However, Zia refused to put this in writing, and in a letter to President Reagan claimed the U.S. intelligence was a “total fabrication,” likely in an effort to save face.

The U.S. Embassy in Pakistan reports to the State Department on a meeting between Ambassador General Vernon Walters and President Zia. Walters returned to Islamabad to warn Pakistani officials that U.S. aid was in “grave jeopardy” after a link between the Pakistani program and Chinese technology was discovered. A U.S. military aid package, which included F-16 fighter-bombers, was also discussed.

In a follow-up message after his trip to Islamabad, Ambassador General Vernon Walters noted that at the end of the conversation with Zia the Pakistani President had given his “word of honor” that Pakistan “will not develop a nuclear device or a weapon.”

Secretary of State George Shultz’s letter to President Reagan covering the history of US responses to Pakistan’s nuclear program and future courses of action by the United States. While each option will rescind United States’ aid money, the Secretary details three different ways to go about it, with varying political implications for each.

A State Department assessment of Pakistan’s security situation, its nuclear program and the future of Pakistani planning. A range of subjects are covered in depth including, Pakistan’s perception of its security situation, major foreign policy dilemmas such as India and Afghanistan, the development of a “nuclear options” and American non-proliferation responses.

A memorandum from Hugh Montgomery, The Director of Intelligence and Research at the State Department to Ambassador Ronald Spiers discussing Indian and Pakistani nuclear proliferation. The Director details tensions between Pakistan and India, potential actions by India to stop a Pakistani nuclear program, and the influence of outside actors such as the USSR, China, and the United States.

A State Department telegram discussing the possible Chinese-Pakistani nuclear assistance and reports that Pakistan had acquired a nuclear weapon in October of 1985.

A letter from the United States Control and Disarmament Agency assessing Pakistan’s nuclear weapons program and US security assistance. Three main issues and possible courses of actions are discussed; they include President Reagan’s “red lines,” certification of Pakistani nuclear activity and convincing Congress to continue aid to Pakistan after September 1987.

A briefing book for the July 15th-21st visit of Pakistani Prime Minister Junejo to Washington. The book covers a wide range of topics including a summary of the US-Pakistani relationship, US and Pakistani goals, visitation schedules and topics for discussion including Afghanistan, Pakistan’s nuclear program and narcotics

A State Department Cable detailing the visit of Pakistani Prime Minister Mohammad Khan Junejo to Washington D.C. According to administration officials, Junejo was “astute and well briefed” and professed to be responsive to the U.S. emphasis on the “absolute criticality” of “restraint” in Pakistani nuclear activities. In meetings with the press, Junejo “specifically affirmed” commitment not to enrich uranium above the five percent level.

A cable detailing a possible plan of action regarding Pakistani nuclear and security concerns. The document includes a brief background on the situation and a three phased strategy with responses on the international stage, the establishment of a Presidential emissary and a “game plan” for Capitol Hill.
