In the morning, Fanfani met with his advisers, and they agreed to accept the Jupiter-Polaris arrangement. He then met with Kennedy for a series of conversations on East-West issues and the developing countries. During their private meeting, Fanfani conveyed to Kennedy the conditions for the agreement—Polaris submarines would not be based in Italy, and Italy would be a participant in the MLF and a member of the NATO committee establishing it. As he noted in his diary, Fanfani asked that language referring to “bases in the Mediterranean” (“which could lead one to suppose they are in Italy”) be removed from the “minute of understanding” of the meeting. Kennedy accepted the stipulations, and a memorandum of their understanding was prepared.

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.

Fanfani covered the events of the day in this journal entry, noting that he told Kennedy he would make no commitment on the Jupiter-Polaris replacement until he spoke with McNamara. With McNamara, Fanfani emphasized the point about using the Jupiter base for space launches. Both Kennedy and McNamara denied that there was a trade with the USSR, with McNamara emphasizing the risks posed by the Jupiters during the Missile Crisis.

Kennedy, McNamara and Rusk moved ahead with the Jupiters matter by making plans to bring it up with Italian and Turkish defense ministers at the NATO meeting in Paris in December 1962. The goal would be to persuade them of the obsolescence of the Jupiters, the dangers that they posed during the Cuban crisis and in future crises, and the need for “better arrangements,” such as “a rearrangement of Polaris deployments.”

President Kennedy continued to monitor the Jupiter missiles problem. During a meeting with Rusk a few weeks later, McNamara explained that President Kennedy, who he had seen in Palm Beach on December 27, had asked him what steps were being taken “to remove the Jupiters.” Consistent with that, McNamara favored the “earliest possible date” and asked whether a “deadline” could be set for April 1 to begin the removals.
