Or maybe that's because India is the largest democracy in the world and has been mostly at peace since its independence in 1947 (minus border conflicts with China and Pakistan and some peacekeeping operations abroad). It's last conflict was in 1999 against Pakistan and the total death toll after 3 months of operations was less than 5000 victims. It's not a bad track record for such a large and populated country given the size of the societal issues it's dealing with.
