Washington, DC - On July 1, 1968, the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) opened for signature in our respective capitals: London, Moscow, and Washington. Today, 50 years later, we celebrate the immeasurable contributions this landmark treaty has made to the security and prosperity of the nations and peoples of the world.

The NPT has provided the essential foundation for international efforts to stem the looming threat – then and now – that nuclear weapons would proliferate across the globe. In so doing, it has served the interests of all its Parties and has limited the risk that the vast devastation of nuclear war would be unleashed.

We also celebrate the astonishingly diverse benefits of the peaceful uses of the atom, whether for electricity, medicine, agriculture, or industry. This boon to humanity thrives because the NPT, and the nuclear nonproliferation regime built around the Treaty, has helped provide confidence that nuclear programs are and will remain entirely peaceful.

The International Atomic Energy Agency (IAEA) plays a critical role in NPT implementation, both to promote the fullest possible cooperation on the peaceful uses of nuclear energy, and to apply safeguards and verify that nuclear programs are entirely peaceful. An IAEA comprehensive safeguards agreement together with an Additional Protocol provide credible assurances of the absence of undeclared nuclear activities and should become the universal standard for verifying the fulfillment of NPT obligations. We pledge our full and continued support to the IAEA and urge others to do the same.

By helping to ease international tensions and create conditions of stability, security and trust among nations, the NPT has made a vital contribution to nuclear disarmament. The NPT continues to help create conditions that would be essential for further progress on nuclear disarmament. We remain committed to the ultimate goal of the elimination of nuclear weapons, as set forth in the NPT, and are committed to working together to make the international environment more conducive to such progress.

The success of the NPT was not foreordained, nor is its future success guaranteed. It depends on our concerted and sustained efforts to ensure compliance, to promote universalization, to ensure effective safeguards, and to respond to ongoing and emerging proliferation challenges, wherever they occur. Even at the height of the Cold War, our predecessors made this wise investment in our shared security and prosperity. Today, we pledge our unstinting commitment to preserving and deepening this legacy for future generations.
