There is no way you can find a peace ful solution to the problem when you have two groups professing the same kind of ethics . Populist tamil extremism on one hand and the lankan hegemony on the other . The only thing that is very clear is that the nature of conflict is definitely different from the ones witnessed during medieval and ancient times. The change in demography has definitely some thing to do(Most "tamils" of present era being the one who came from deccan during the rule of vijayanagar dynasty).
