Noting that the same objections to the NPT remained, INR opined that some West German politicians were using them “to rationalize an opposition that is really based on nationalistic emotions and on the political advantages to be derived from playing upon these emotions.”

In this report, the INR commented on Soviet policy language regarding nuclear proliferation. They called Soviet Ambassador Anatoly Dobrynin's criticism of MLF proposals "absurd," telling Secretary Rusk that “in no way can we be blamed for taking steps which even with a most fault-finding approach would look like disseminating nuclear weapons."

In this report, INR noted that the French had walked back statements by Charles de Gaulle in January 1963 that he would not object to the development of a West German nuclear capability. This report also includes notes on why the French opposed an MLF, claiming Washington might be "whetting the German appetite" for a national nuclear capability.

INR assessed several recent newspaper articles by Kiichi Saeki, a defense expert close to the government, whose thinking was “noteworthy for [its] frank consideration of Japan’s need for nuclear-defense planning to cope with Communist China’s growing potential.”

By the late winter/early spring of 1967, controversy over the NPT was hurting U.S.-West German relations, placing them at perhaps their lowest point during the Cold War. While an earlier report suggested that West Germany would ultimately sign the Treaty, despite objections, only weeks late INR this report was issued wondering whether Bonn was trying to wreck the NPT.

INR analysts pointed to events during mid-February 1963 which suggested that the Soviet leadership was taking steps to spend a greater share of the gross national product on military resources.

This “Limited Distribution” report on possible Japanese reactions did not anticipate that a test would cause basic changes in US-Japan security relations or in Tokyo’s general approach to nuclear weapons.

Before the words “nuclear nonproliferation” entered official discourse, the term “non-diffusion” (or “non-dissemination”) of nuclear weapons was used routinely. In part stemming from the negotiations over Berlin, during 1962-1963 the Kennedy administration held talks with allies and adversaries on the possibility of a non-diffusion agreement which included Germany. In light of a recent Soviet proposal, INR veteran Soviet expert Sonnenfeldt explained why Moscow had moved away from earlier proposals singling out West Germany and was focusing on the general applicability of a non-diffusion agreement.

At the request of Undersecretary of State John Irwin, the Bureau of Intelligence and Research (INR) prepared an assessment which included a detailed review of Indian’s nuclear facilities and their capacity to produce weapons-grade plutonium as well as capabilities to deliver nuclear weapons to a target. While India had signed agreements with Canada and the United States that nuclear reactors were to be used for peaceful purposes, the Indians were likely to claim that an explosive device for “peaceful” purposes was consistent with the agreements. Whether the Indians were going to test in the near future was in doubt. INR could not “rule out” one in the near future. Further, the “strongest incentive [to test] may well be the desire for the increased status of a nuclear power.” All the same, “it our judgment that a decision to authorize a test is unlikely in the next few months and may well be deferred for several years.” Weighing against a test were the financial and diplomatic costs, for example, “India's full awareness that assistance from the US and other countries (possibly including the USSR) would be jeopardized.”
