I could have agreed with you if India could stop sponsoring insurgencies in Chittagong Hill Tracts and stop border killings.
Its not really important that members on an anonymous forum agree with each other or not.
But the realities.
Which is that India in not interested in fostering new arms races in its region, where none are really needed.
Also, as has been seen historically, in the distant past from 1971 and more recently with the Rohingya exodus, any armed conflict in the region will result in an exodus of refugees into India.
That is something India would like to avoid peacefully as far as is possible.
