That's something only Indian citizens and people living in India can decide. Outsiders may have opinions, but they cannot override the will of the people who have a legitimate standing in the matters of the state. And note how I included "people living in India" here. Legitimacy is a fuzzy concept. Citizenship is a legal category, and it should not matter for legitimacy as such. But it is widely accepted that citizens living outside their country still have a legitimate standing in the matters of the country. But beyond that, a legitimate government should serve the interests of the people factually living within the country. India does not have a large non-citizen population, and the distinction is mostly irrelevant with them. But some other countries do. If their governments only serve the interests of their citizens, they are fundamentally illegitimate.
