Corroding nation-state and republic

What did Gyanendra or his predecessors do other than suppress the people for their interests?

Is the traditional concept of nation-state, especially defined by the Treaty of Westphalia (1848), valid today? The answer would be no, as the conventional concepts and practices of nation-states are fast changing. Neither nation nor state is fully manifested in politics. If the nation is more or less related to the emotional and cultural aspects of the state, the latter underscores the significance of sovereignty, territory, government and people.
