In his diary, Fanfani recorded that the Council of Ministers has approved his report on the talks with President Kennedy and the recommendation to withdraw the Jupiters on April 1, 1963. The Ministries of Foreign Affairs and Defense would have a “mandate” to implement the withdrawal. As agreed, the Jupiters would be replaced by Polaris, and the latter would not be based in Italy. Italy would support a NATO multilateral force, without the tripartite directorate that De Gaulle had espoused.

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.

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.
