Pakistan is there. It is on India’s western border (and until 1971 was also on the eastern border). It cannot be wished away; nor can India pretend it will go away. On the very day the two countries became independent, they inherited a clutch of problems that was the inevitable result of Partition. I know of no example in history where two countries born out of a division of land lived in peace ever after.
