Nonproliferation talks entered their decisive phase after the submission of a joint U.S.-Soviet draft to the ENDC on February 21, 1967. One week later, High-Commissioner of the French Commissariat à l’énergie atomique, Francis Perrin, assessed France’s options. It was not “by accident,” he noted, the original five UN Security Council permanent members—the United States, the United Kingdom, France, the Soviet Union, and China—were in line for nuclear-club membership: “…they are the same profound reasons, of a geographical, demographic or other nature, which led to the choice [in 1945] … of the countries with special responsibilities in the maintenance of world peace.” After noting how advances in “India, Israel, Japan, Sweden, and also West Germany” portended the further spread of nuclear weapons—and acknowledging France had itself sought help with its weapon program—Perrin pondered whether proliferation might hasten nuclear disarmament by convincing the superpowers of its merits. In the end, however, fear of a “large and hostile” nuclear-armed PRC made him pessimistic. While he did not advise signing the NPT, it would be “very important” for France to affirm publicly, if unilaterally, “its constant policy since 1958 … not to cede any atomic weapon or any atomic explosive device to a country which does not possess it, and not to help any such country to manufacture them.” He dismissed internal opposition toward the NPT as defensive—"an a posteriori justification of the French decision to constitute an atomic armament." More significant was the likelihood West Germany would gain its own atomic arsenal, jeopardizing France’s “dominant political position among the Europe of the Six” members of the European Communities and reviving Cold War tensions in Europe. He finished with an eye-opening analysis of how the Kosygin proposal for nuclear-weapon states to extend negative security guarantees to non-nuclear-weapon states’ signatory to the NPT would not impede the use of French nuclear armaments against a West German blitzkrieg backed by the United States.

The finalization of a completed draft nuclear nonproliferation treaty, which the ENDC transmitted to by the United Nations without endorsement on March 18, 1968, launched a French review of the NPT’s implications for international law. The draft NPT was accompanied by a proposed United Nations Security Council Resolution (UNSC), whose soft guarantees against nuclear-weapon use or threats had been a compromise workd out between Washington and Moscow. An initial study by Foreign Ministry lawyers identified numerous “juridical reasons… to fight against a project that, in its letter if not its spirit, constitutes a revision of the [UN] Charter." The report elaborated on how the hierarchization of “forms of aggression” would “downgrade” non-nuclear (i.e. conventional) violence. Non-nuclear-weapon states treaty signatories would receive non-binding security guarantees. The “Anglo-Saxons and Soviets” would maintain “freedom of action as far as what measures they choose to adopt.” Although the French government’s foremost legal experts opted not to advise vetoing the UNSC resolution, they warned the NPT package could serve as a warrant for nuclear-armed permanent members of the UN Security Council to wage “preventive war” in the name of worldwide nonproliferation.

 This short research note briefly explores the case for and against vetoing the UNSC resolution. As the United States, the United Kingdom, and the Soviet Union were serving as co-sponsors, and the Republic of China on Taiwan would welcome any international measure the People’s Republic of China opposed, France was the only state in a position to veto the UNSC resolution and perhaps torpedo the NPT when the UNGA special session met in late April. If France were to abstain, it would be henceforth bound by the resolution. Even so, the report cautioned whether “a negative attitude” should outweigh “the downside of defeating a project whose intention, if not whose content, fulfills the wishes of the vast majority of non-nuclear delegations.”

Edward Biegel of the Bureau of Western European Affairs answers Undersecretary Ball's questions on French nuclear ambitions and Western European collective security. He makes the arguments against nuclear sharing, and also mentions the fact that a Baltimore Sun article likely alerted the Soviets to the fact that the US deployed tactical nuclear weapons on the German front.

Discussion between Galley and Blancard with Kissinger, Foster and Sonnenfeldt held in secret. Kissigner wishes to give the strategic assessment of France followed by Foster’s specific observances. Kissinger notes that the Soviets are expanding rapidly, and there is a need for a warning system. They discuss the importance of building up a deterrent, and the U.S. thinks it is feasible to assist the French in this regard. The French are asking for clarifications and information on MIRV and MRV. Kissinger discusses how these exchanges are not going through the normal channels, stressing the need for secrecy, though Congressional approval may be needed for some points, and they conclude by setting up a time for Foster to come to France.
