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.

Analysis of the military campaign waged in Southern Angola in 1987-88 as well as the lessons learned from this exchange. Document indicates that FAPLA failed to learn from its mistakes, while UNITA adapted much more effectively to the combat environment it faced in Angola. Although FAPLA managed to hold on to Cuito Cuanavale, its large losses led to a Cuban build-up in Southern Angola, which challenged the existing military balance in the region. This provided new impetus to peace negotiations and resulted in the December 1988 Accords among South Africa, Angola and Cuba.
