Peace activist
Every year since 2000, Nayar had been leading peace activists to light candles on the Independence days of Pakistan and India at the Attari-Wagah India-Pakistan border near Amritsar. He was a close friend of another Pakistani politician ch. Jaleel Ahmed Khan. Who arranged the launch of Nayar's book in Avari hotel Lahore in 2013. Both of them participated in various peace enhancing events in both countries as ch. Jaleel Ahmed Khan a senior Pakistani politician who migrated from India in 1947 also strongly advocated peace between the two neighboring countries. He had been working to free Indian prisoners in Pakistan and Pakistani prisoners in India, who have completed their sentences, but have not been set free. He had started a tradition of candle vigil since 1995 at Indo-Pak Wagah Border during midnight of 14–15 August for India-Pakistan Peace through celebration of Independence Day and remembering people of both sides. In later years of his life, he could not participate in this due to his old age but inspired many young folks to continue the tradition. Ten days before his death, he had flagged off 'Aman-Dosti Yatra' which was a 40-member delegation of Aaghaz-e-Dosti that marched from Delhi to Wagah Border under leadership of Aaghaz-e-Dosti founder Ravi Nitesh and Gandhi Global Family's Secretary Ram Mohan Rai for lighting candles for Indo-Pak Peace and thus continued his legacy. This was his last public presence.
Political commentator
As a political commentator, Nayar wrote his views freely on most politically current issues. He had supported the movement of Anna Hazare and chided the Pakistan Government for not apologising for the army atrocities in East Pakistan in 1971 that led to the formation of Bangladesh, and for allowing drugs to be smuggled into India. Nayar has been accused of supporting anti-Indianconspiracy theories. In a Feb 2010 article in Pakistani newspaper Dawn, he alleged that the Indian anti-terrorism squad leaderHemant Karkare was murdered by Hindu right-wing activists. In July 2011 US Authorities confirmed that Nayar attended many events in United States hosted by and supported by Syed Ghulam Nabi Fai, which had been funded by Pakistan ISI.
