When you watch "Future Weapons" on the Discovery Channel.. it is amazing the way American scientists are so focussed and innovative in developing strategic missiles like the MOAB (Massive Ordanance Bomb - nicknamed "Mother of all Bombs") which pack awesome destructive capabilities but are used as deterrent against any sort of mis-adventure...
India should raise the salaries of the Defence scientists astronomically to prevent brain-drain from India to countries like the US. Indian scientists pack enormous amount of ingenuity and skillsets but run off to the US because it is there, that their skills are amply reimbursed.
It is a pity that Indian government is so focussed on its internal bickerings that we are actually turning a blind eye to the enormous amount of brain-drain happening to India. If we stopped this brain-drain, then I am sure India would be miles ahead of countries like Pakistan, which is presently matching India step to step, in defence initiatives. I am sure if India can retain its scientists financially and morally, Pakistan would soon be left behind running on a bullock cart while our scientists take us ahead on a Ferrari...!!!
