On 11 November 2005 , speaking on the 40th anniversary of IDSA 's founding , Prime Minister Manmohan Singh singled out Subrahmanyam for his achievements : Incidentally , Subrahmanyam was on board an Indian Airlines flight ( IC 421 ) on 24 August 1984 when the plane was hijacked to Lahore , Pakistan and onward to Dubai where all passengers were released without incident . The arrested hijackers later claimed in court that it was Subrahmanyam who " planned the entire hijacking to examine nuclear installations in Pakistan . " Subrahmanyam was appointed the Convenor of India 's first National Security Council Advisory Board ( NSCAB ) , established by the Atal Bihari Vajpayee government in 1998 . The board drafted India 's Draft nuclear doctrine , which governs all policy aspects with regard to usage and deployment of India 's nuclear arsenal . Its most significant aspect was the declared ' No first use ' policy , and the consequent directive that India 's nuclear weapons would largely be oriented around a second strike capability . Subrahmanyam had been an old proponent of India adopting a no first use posture , arguing for it right after the Shakti tests in 1998 , and even earlier in 1974 . The nuclear doctrine was adopted by the government of India soon after
