Pak mistakenly identified the name Prithvi with Prithviraj Chouhan without knowing that Prithvi is primarily named after an element that is earth.
As a symbolic counter Prithvis counter version was named as Babar and Ghazni etc. But the sad part is both Babars and Ghaznis rampage occured against the natives of current Pakistan and their great great great..... grand mothers were raped and their great great great....... grand fathers were butchered! It is an irony that we name barbarians as our icons!
Anyway, even the Indians also name their weapons as per Hindu mythological characters! For Eg: Indian Tank is called Arjun!
An Indian missile can be of any name but if the name of an element is given atleast as a symbolic gesture atleast one of them could have been named with an Urdu, which is an Indian language than Pakistani, name instead of all sanskrit names!
There is nothing really in a name, but it displays a percieved tilt and that does not go unnoticed!
India as a pluralistic society could have had all its faiths names for its weapons, projects etc. It will not lose anything but only go up in the eyes of the world far more higher!
