This letter, written from Jim MacCulloch at the British Embassy in Bonn to Robert Alston at the FCO's Joint Nuclear Unit, details a recent memorandum sent to West German Chancellor Helmut Schmidt by Menachem Begin about the Pakistani nuclear program.

This document has three parts. The first part, a letter written from Bryan Cartledge of the FCO to Stephen Wall, discusses recent correspondence from Israel's Prime Minister Menachem Begin to British Prime Minister Margaret Thatcher. The document's second and third parts are PM Begin's letter, along with an accompanying Israeli intelligence report regarding Pakistan's nuclear program.

This document is a record of a joint Anglo-American meeting on March 16, 1979, regarding the nuclear situation in Pakistan. A significant point of discussion was the alleged support being given to Pakistan's nuclear program by both Libya and Saudi Arabia.

The FCO’s Joint Nuclear Unit (JNU) assessed the Panorama documentary as correct in broad terms, but speculative and inaccurate in most details. Analysts contended that the most significant allegation was that of the Libyan/‘Islamic’ bomb, but that there was still no substantive evidence that Libya had provided finance or that Pakistan had agreed to proliferate. Anonymous allegations in the documentary were said to be ‘sensational’ but carried ‘little conviction’.
