What do we learn from the two stories of Belgium and Srilanka?

We learnt following things from the example of Belgium and Srilanka:
(i) In Belgium the leaders realised that the unity of the country is possible only by respecting the interests of different communities and religious.
(ii) Such a realisation resulted in mutually acceptable arrangements for sharing power. It helped to avoid civic strife between two communities and a possible division of the country.
(iii) Srilankan example shows us that if a majority community wants to force it dominance over others and refused to share power, it can undermine the unity of the country.
