Changes

The plan for a nuclear NATO threatened to scuttle the talks altogether, and the United States eventually abandoned it in favor of reaching a workable treaty. A more difficult problem involved the question of bringing non-nuclear nations into line with the planned treaty. Nations that had not yet developed nuclear weapons technology were essentially being asked to give up all intentions to ever develop the weapons. Without this agreement on the part of the non-nuclear powers, having the nuclear powers vow never to transfer the technology would likely not result in any real limitation on the number of worldwide nuclear powers. After two years of negotiations, the nuclear powers managed to make enough concessions to induce many non-nuclear powers to sign.

The final treaty involved a number of provisions all aimed at limiting the spread of nuclear weapons technology. First, the nuclear signatories agreed not to transfer either nuclear weapons or nuclear weapons technology to any other state. Second, the non-nuclear states agreed that they would not receive, develop or otherwise acquire nuclear weapons. All of the signatories agreed to submit to the safeguards against proliferation established by the International Atomic Energy Agency (IAEA).
