The events of recent weeks provide what could be a possible blueprint as to how India will cease to be in existence. All that is needed is retaliation by other states. So when Maharashtra goes after NorthIndians, they could in turn go after South Indians who could in turn go after the North Indian. During stray violence, Maharashtrians and Tamilians get killed in Karnataka, causing South Indian violence on each others. Sikhs start attacking nonSikhs in Punjab due to the attacks on them all over the country, causing an exodus there. Everyone get tired of "Mera Bharat Mahaan" and set up their own states. Belgaum ehtnic Maharashtrians and Bangalore ethnics Tamilians are sent packing, setting the stage for future border wars.
All this requires is the presence of three powerful jokers. We are dangerously close to such a scenario now, the two jokers in the pack right now are Raj Thackeray and Lalu Yadav. Firm government intervention is needed to address this threat to national integrity.
India is the cake that everyone takes for granted. There is a lesson to be learned from Yugoslavia here.
