Bloodbath in Sri Lanka

Now, as the LTTE (Liberation Tigers of Tamil Eelam) is fighting for a Tamil state in the north and eastern part of Sri Lanka, the country is on the brink of a total disaster. I am wondering about the future of major separatist/ insurgent movements in South Asia in the coming years.
Sikhs, Kashmiris, Tibetians, Balochis, Arakanis etc have unsuccessfully sought various degree of autonomy for decades. Almost all these movements originally had a socio-political-economic basis but were later adopted or hijacked by a radical religious ideology.
Deeply worried Tamil faces in Oxford and London in the last few weeks remind me of the terrible mental agony of my parents in the hopeless last week of March and April 1971 in Pakistan army occupied Dhaka city.
With the greatest respect, I remember Bangabandhu and Tajuddin Ahmed for their wise political leadership during that crisis.
