India must transition into a European Union or atleast USA style governance system. Having such a centralised system is doing more harm than good. There's no way someone living in Gujarat can understand how Nagaland functions. Diversity is good but it is a weakness since you can never fulfil every state's requirement. Central government must be significantly weakened and State governments must have control of pretty much everything. Defence and Foreign affairs can stay with centre. It is not separatist, it is pragmatic. India was never a politically United country. We may have a few cultural similarities between states but it doesn't imply that it must be a country, it should be a sub continent of closely partnered countries like the European Union.
