It is specious to say that India has not invaded anyone in past 3000 years are so. The idea of India as a country is a fairly recent one. May be with some liberty we can consider 1857, year of Sepoy Mutiny as the starting point for idea of India as a single country. Prior to that the vast territory was divided among kingdoms battling against each other (Cholas against Chalukyas, Vijayanagar Empire against Bahamni Kingdom, Tippu against Marathas and so on).

The idea of India is not new. The idea that a country has to be politically united as a single country is new. If you read any significant Indian literature, you will notice there is a feeling of unity.
