Members of the Nassau Decisions Steering Group worked up the texts of letters from Secretary of Defense Robert McNamara to the Italian and Turkish Defense Ministers, which President Kennedy approved when he met with Dean Rusk and Thomas Finletter in Palm Beach on January 5, 1963. The State Department sent the letters later to Ankara and Rome later that day.

McNamara’s letters expand on the points about the need to replace Jupiters with Polaris missiles that he made to Andreotti and Sancar when he met them in Paris. To both, McNamara wrote that the Polaris force would be “on station” by April 1 as the replacement for the Jupiters. Writing to Andreotti, he also mentioned substituting “obsolete” Corporal with Sergeant missiles. In his message to Sancar, McNamara informed him that he is exploring the possibility of accelerated delivery of the F-104s and that “emergency actions” could make it possible to deliver the first squadron during April 1963.

During his meeting with Turkish defense minister Sancar, McNamara raised the risks posed by, and to, the Jupiter missiles and the need to withdraw those “obsolete” missiles and replace them with Polaris SLBMs. Turkish officials would play a role in targeting the missiles at NATO military headquarters. Worried about the implications of withdrawing the Jupiters, Sancar expressed concern about the impact that removal of the missiles would have on Turkish “confidence” in the U.S., the need to avoid “moral depression” (meaning morale) among “the people or the army” and stressed that the U.S. (“the best of allies”) was leaving Turkey “to a condition of ‘aloneness.’” McNamara did not believe that substituting Polaris for Jupiters would have that impact. Both agreed on the importance of proceeding in secrecy.

When Sancar observed that the late delivery of F-104G’s would adversely affect morale, McNamara said that an earlier date would be possible and suggested the possibility of announcing earlier delivery with the removal of the Jupiters. McNamara added that “time was of the essence.”

The State Department later sent a telegram to the ambassadors in Italy and Turkey reporting on McNamara’s meetings with Andreotti and Sancar.

In a meeting with Italian Defense Minister Guilio Andreotti, McNamara had several matters to raise, but soon brought up the Jupiters and the need to “substitute something more responsive and less vulnerable to sabotage or direct attack.” When Andreotti raised the possibility of a naval deployment, McNamara agreed, suggesting assigning Polaris submarines to SACEUR (Supreme Allied Commander Europe), “with an Italian role in the targeting.” Suggesting that the U.S take the initiative on the matter, Andreotti preferred that it be settled before the spring 1963 elections.

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.

Seymour Weiss would push back against any efforts to remove the Jupiters, but he and others realized that President Kennedy had a “keen interest” in the matter and that Secretary of Defense McNamara had ordered that action be taken (assigning his General Counsel John McNaughton to take the lead). Nevertheless Weiss and Assistant Secretary of State William Tyler presented Secretary of State Rusk with a memorandum making the case against action on the Jupiters or at least postponing their removal until a “later time.” Paralleling arguments made during the crisis by Ambassadors Hare and Reinhardt, Tyler pointed to the “symbolic and psychological importance” of the Jupiter deployments. While Tyler noted parenthetically that the Italians had “given indications of a disposition to work toward the eventual removal of the Jupiters,” the U.S. could not phase them out “without general Alliance agreement,” including Italy and Turkey’s consent, “unless we are prepared to lay ourselves open to the charge of abrogation of specific or implied agreements.” Rusk was in the know on the secret deal, but his reference to a “later time” was consistent with it and signing the memo would have placated Tyler and Weiss.

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.

The note describes the proposal made by MacNamara as the most recent element of the US political-strategic thinking. The document explains MacNamara's proposal from its origins to the current situation. The document analyzes the position of various countries, with a focus on the Italian one and some points which still need to be sorted out. Italy seems interested in participating in the proposed Committee.

The telegram announces that the Italian government welcomes MacNamara's proposal of establishing a restricted Atlantic Nuclear Committee. This proposal is in the context of a necessary widening of the Atlantic nuclear responsibilities that now are concentrated in Washington.

The note is about MacNamara's proposal to establish a Special Committee in order to broaden Allies' participation in the strategic planning of US nuclear deterrent and to reach a more efficient process of political consultation. The document outlines some points related to Italy's position.
