This is what exactly to be done by Indian Government as well with out allowing itself to be bullied over by the caste,religion,region, political parties, minorities etc etc. "Be a Roman when you are in Rome" is the dictum that tamilians should practice when they are in Sri Lanka. It is not a very distant past when people of Andhra Pradesh were discriminated as second rate citizens by Tamilians in a composite Madras State. So, National integration is supreme over all other considerations in a small country like Sri Lanka. One should love the land where you live. Former Prime Minister Morarji Desai clearly stated that India has no business to interfere with the goverance of Sri Lanka when his attention was drawn to the so called discrimination of Tamilians settled in Sri Lanka.
