Intelligence reports about recent visits to Beijing by Pakistani defense and science officials raised questions whether China was or would be providing nuclear aid to Pakistan. The latter was already developing close relations with China, a matter which was of great concern to U.S. policymakers, but INR analyst Thomas Thornton concluded that Pakistan was highly unlikely to seek a significant degree of Chinese nuclear assistance.

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.

Despite the concerns about sharing the ALR-69 radar warning receiver with Pakistan for fear of it falling into Chinese hands, CIA officials argue that failure to meet Pakistani demands would lead to a “serious blow to U.S. worldwide nonproliferation efforts.”

With delivery of U.S. F-16 fighter-bombers imminent, Pakistan threatens to refuse delivery unless the U.S. agrees to include the ALR-69 radar warning receiver for the aircraft. CIA analysts have concerns that including this sensitive radar technology in the delivery of the F-16s would enable China, a close military ally of Pakistan, to obtain and study the device.

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.

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.
