(Indian Express)

Leading Indian nuclear weapons experts are debating whether India should join the CTBT, deriving their arguments from contradictory interpretations of the 1998 Pokhran-II nuclear tests results.  Former coordinator of India's nuclear weapons programme K. Santhanam argues that the failed test in 1998 requires new testing and that India should therefore not sign and ratify the CTBT.  Other experts including former President A. P. J. Abdul Kalam and former Head of the Indian atomic energy commission Rajagopala Chidambaram maintain that the tests were successful and that no further tests were needed.

Kimball emphasizes the need for U.S ratification of the CTBT: "Without U.S. ratification of the Comprehensive Nuclear Test Ban Treaty, our ability to harness the international support necessary to prevent nuclear terrorism and strengthen the beleaguered nuclear nonproliferation system will be greatly diminished."
