"ghar vaapsi" - so should the UK and the USA also apply this principle and send all the desis back to India? In the west, "ghar vaapsi" is called racism. The concept of a "nation state" which you are buying into was a colonial invention. Talk of "losing territories" is pure colonialism - India was *never* a nation state (politically united territory) before colonialism. This colonial concept is the cause of the problem. There will never be such a thing as a shuddh / pure society - others have tried it before (Hitler, Rwanda) - it is called "genocide".
