The Republic of India is one of four powerful non-aligned nations.  Bordering Persia in the west and China to the northeast, they began practicing neutrality after finishing their part of the Islamic Jihad.  They have colonized a small number of systems, maintain a small navy, and keep to themselves as much as possible.  They do not ignore the outside universe.  They simply see no need to compete with us.  They feel secure.  It makes them interesting to deal with.
