President Bush and Prime Minister Manmohan Singh of India signed a statement of intent in 2005 to allow India access to civilian nuclear technology, despite its not being a signatory to the Nonproliferation Treaty. This deal would reverse decades of U.S. nonproliferation policy, since India was the source for much of U.S. law on this count. It would require Congress to amend that law to create special exceptions for India. Rationales and critiques of the proposed deal have focused on its impact on the future exercise of U.S. authority on nonproliferation policy worldwide. But the broader impact may be felt internally, since nonproliferation decisions have been inextricably linked to national security imperatives. In acknowledging an economic justification for allowing India access to nuclear energy, the deal has also created a new dependency between U.S. national security policy and the energy profile of emerging powers.
