The two leaders signed off on a “minute of understanding” expressing their understanding on the MLF, replacement of Jupiters with Polaris by April 1, the substitution of Sergeant for Corporal missiles, and the possibility of using the Jupiters for “space experiments.” In accordance with Fanfani’s request, the minute was retyped to leave out the reference to bases in the Mediterranean.

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.

Prime Minister Amintore Fanfani’s visit to the U.S. was an opportunity for he and President Kennedy to reach “a meeting of the minds” on the Jupiter-Polaris problem. The two had several conversations during the next two days on East-West relations, NATO nuclear issues, and the developing world, among other topics.  During this conversation, with only the U.S. translator present, Kennedy explained to Fanfani that Polaris/Sergeant missiles as a replacement for Jupiter/Corporals, along with Italian participation in an eventual MLF, should be announced as “whole package” rather than to have “the different points of decision simply leak out, without coherence and possibly at the wrong moment.” He believed that the main elements of the agreement would find “general approval” among most political groupings in Italy. When Fanfani brought up the possibility of announcing the U.S. request on Jupiters and Polaris and then taking it to his government, Kennedy emphasized the need for quick action, adding that it would “not be desirable to allow for prolonged discussion” of the package.

At Fanfani’s request, Kennedy explained the arrangements for Polaris missions in the Mediterranean, which operated out of a base in the Iberian Peninsula (Rota, Spain), and the various options for an MLF, either surface or submarine ships. Such an approach, Kennedy believed, was a way to improve the “position of the West.” Accepting Kennedy’s assertions about the dangers of the Jupiter missiles, Fanfani nevertheless saw a “psychological” problem involving the “prestige and strength” of Italy’s armed forces. Kennedy “indicated lively interest” in Fanfani’s question as to whether the Jupiter bases could be used for “cooperative peaceful space efforts.”

At the meeting’s conclusion, Kennedy “stressed that by the following morning they should be able to combine four or five points into a proposal that would strengthen the Italian and American position within the framework of the Alliance, thus making this meeting a gain in its cohesiveness and hence political strength.”
