Cannon unto Canon is a collection of papers that Mr. Diljit Singh Pannun prepared as a political thinker to enable the political bosses and their bureaucratic assistants to have the feel of difficult situation prevailing in the Punjab during the first half of the decade of eighties of the last century, from the national perspective. The papers present an incisive analysis of the Sikh Psyche and Punjabi Hindus’ response thereto. In the process, Mr. Pannun draws a road map for possible solutions to push the Punjab polity put of the quagmire into which it had been stuck-up. Surprisingly, the same route was adopted to sign the Rajiv-Longowal Accord.
