During the luncheon for Fanfani, Bundy sent Rusk this short memo about the Fanfani-Kennedy conversation, noting the former’s concern that removing the Jupiters could lead to attacks from the right about “softness toward left-wingers who want the missiles out.” When Kennedy spoke with McNamara after the meeting, he asked him to emphasize to Fanfani the military advantages of replacing the Jupiters with Polaris. McNamara wanted to emphasize that very point to offset any talk of a “nefarious Cuban bargain” with the Soviets. Bundy also highlighted the debate between George Ball and McNamara over whether Jupiters and Polaris should be mentioned in the communique on the Fanfani-Kennedy discussions.

During this conversation Wilson, McNamara, Rusk, and Ball continued the discussion of the British proposal for an Atlantic Nuclear Force, including possible command arrangements. Other topics included the impact of the Chinese nuclear test and a nonproliferation agreement.

This memorandum details an extensive conversation between representatives from the U.S. and Great Britain about President Kennedy's decision to cancel work on "Skybolt," or a surface-to-air missile that the British were invested in. The meeting was an attempt to placate a "looming crisis" in Anglo-American relations.
