Also, one of the aspects that is generally not brought out in favor of DRDO is following. Suppose you go to the international market and then say ..you want this sort of missile..you will find many interested people to sell you..but the cost would be so high..that you simply can not afford it...now once DRDO starts developing this sort of missile...and tests it..suddenly the same companies would be coming back to you saying we are going to sell you the same stuff in one third of the price..so in a way..DRDO spent the resources on developing the technologies..the product is not perfect...but still you have got a negotiating power on your side by virtue of that...
