Is india merely a space?

Yes, it has existed in its current form for 62 years and can exist even in future. Indian minorities are by & large happy as they have opportunities for growth and development. This has been proved time and again by the success of the Indian democracy.

Contrast this with Pakistan which could not exist in the form in which it was created. Remember 1971 ?? There was persecution of Bengalis which ended up splitting the country. While Pak may not have as many insurgent movements as India, the 2-3 that it does have are vastly capable of further breaking the country.

So thanks a lot for your concern about India, but we are absolutely capable of protecting our nation.
