Nuclear terrorism a challenge, non-proliferation regime hasn't succeeded: Manmohan

"We are committed to a voluntary, unilateral moratorium on nuclear testing. As a nuclear weapon state and a responsible member of the international community, we will participate constructively in the negotiation of a Fissile Material Cut-off Treaty (FMCT) in the Conference on Disarmament," he said. 

"Global non-proliferation, to be successful, should be universal, comprehensive and non-discriminatory and linked to complete nuclear disarmament," the Prime Minister said, pointing out that there was growing international acceptance for this viewpoint.
