We now have the 123 Agreement. It explicitly states in Article 2 that ‘Each Party shall implement this Agreement in accordance with its respective applicable treaties, national laws, regulations, and license requirements concerning the use of nuclear energy for peaceful purposes.’

In the case of the US, the relevant ‘national laws’ include the original Atomic Energy Act of 1954, the Nonproliferation Treaty Act, and the Hyde Act of December 2006.

To take just one example, the very Section of the 1954 Act under which the ‘123 Agreement’ is entered into — Section 123 — states that, should any nuclear device be detonated for any reason whatsoever, not only shall all nuclear commerce be halted with the country, the US shall have the right to demand the return of ‘any nuclear materials and equipment transferred pursuant’ to the agreement for cooperation as well as any ‘special nuclear material produced through the use thereof if the cooperating party detonates a nuclear explosive device.’ ‘For any reason whatsoever’, the Joint Conference of the two Houses made explicit, shall also include ‘for peaceful purposes’ — the ground we had invoked for the 1974 test! This provision is re-emphasised in the Hyde Act. Section 106 of the latter states explicitly, ‘A determination and any waiver under section 104 shall cease to be effective if the President determines that India has detonated a nuclear explosive device after the date of the enactment of this Act.’

As for ‘applicable treaties’ the US Act to operationalise the Nuclear Nonproliferation Treaty binds the US not to directly or indirectly — and we shall soon see the significance of these two words, ‘or indirectly’ — assist any Non-nuclear Weapon State to acquire or manufacture nuclear weapons. That in devising its cooperation with India the US must adhere to its obligations under this Article is reiterated and emphasised in the Hyde Act. That is why Section 104 of the Hyde Act explicitly states, ‘Pursuant to the obligations of the United States under Article I of the NPT, nothing in this title constitutes authority to carry out any civil nuclear cooperation between the United States and a country that is not a nuclear-weapon state party to the NPT that would in any way assist, encourage, or induce that country to manufacture or otherwise acquire nuclear weapons or nuclear explosive devices...’
