That the Commander of U.S. European Command (CINCEUR), Gen. Lyman Lemnitzer, was a critic of the Jupiter removals may have informed a Joint Chiefs of Staff decision to send him a background paper explaining U.S. decisions that could also be used for discussions within NATO.   The backgrounder provided information comparing the reliability, vulnerability, and survivability, among other features, of the Jupiter and Polaris missiles. While the withdrawal of Thor and Jupiter missiles reduced Western “nuclear potential,” those reductions would be offset by an increase from 350 to about 800 U.S. strategic ballistic missiles, “some of which will be assigned to NATO targets.” Further, it “may be assumed that there will be no reduction in the present expectation of timely damage to the ACE [Allied Command Europe] targets presently covered by the Jupiters.”

Ambassador Hare met with Turkish Foreign Minister Feridun Erkin about moving ahead on substituting Jupiter missiles with Polaris, emphasizing the “importance in Turkey’s getting in on ground floor of this significant move toward a stronger NATO.” Erkin implied that he was “impressed by the reasonableness of our proposals,” but believed that the public would have to be persuaded “that Polaris would be as effective as Jupiters in assuring security of Turkey.” Hare observed that visits to Turkish ports by Polaris submarines armed with ballistic missiles could help maintain Turkey’s “confidence” in the U.S. deterrent and in NATO.

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.
