How do you decrease the lethality of a missile? How do you rationally measure 'lethality' - Is it accuracy, speed, warhead TNT equivalent ...or as in Lahorilogic, how big, tall and green it is. How can you decrease that to make it a controlled environment. Stop making a fool of yourself, you do not know anything (which is okay, most of us do not know enough) but you are acting all knowledgeable (and sadly it shows you are not). So grow up, get off your ego trip. As someone mentioned, this is not a nukkad where yoy say and accuse people or organization without thinking through the allegation. Prithvi is not a vaccine, of which you can take a less lethal dose.
Common Fanne. You are so intelligent and you don't know how to decrease the lethality. It is very easy. Start experimenting with Diwali crackers and extapolate it to Prithvi and Agni. It is that simple.
