Good original thinking Tshering. Defense education should be part of school curriculum in line with inculcating nationalistic fervor. What should be a part defense education taught in school? Possibly India's historical wars which is anyways taught but also adding in a military analysis for victories or losses and not just the political perspective. For example adding in a tactical military reason for the debacle in 62 along with the overall geo-political analysis of the war and its aftermath would start inculcating defense thinking right from the beginning. Thus preparing them mentally for the services.
Applications of the sciences in weapons can also be added as students advance. The $100 Negroponte OLPC or the the new $35 ipad clone can inculcate young minds with an understanding and love for tech and as a gateway to greater information and learning but they must also realize that the $35 tablet running a stripped down Linux OS with SSD storage, firewire , USB , wifi-802.11 capability that they hold is not much different than the systems that run the avionics, control hydraulics and actuators of any modern fighter aircraft, the C&C / guidance of missile systems, Radars and the SCADA systems that control the motors and environment systems of modern ships. If these kids can understand and put together all the subsystems that go into that dirt cheap tablet then extrapolating from that to a LCA Tejas or F22 should be child's play when they are older.
ISRO has realized the need for this with the Aerospace Institute to build future Rocket scientists. A great vision from arguably the greatest Indian rocket scientist till date - APJ Kalam now being fulfilled. But who says this cant be done when the students are younger? Understanding IC engines or the basics of thermodynamics can be done much earlier than it is now.Extrapolating to rocket and jet engines then is much easier.
This would truly build a future generation of strategic and tactical thinkers along with the technical acumen to not only fight in modern electronic battle spaces but also build products and services for the modern marketplace. A Nation is only as strong as its People and its Industry not its Standing Armies. Once this is realized it would be a paradigm shift of amazing proportions. And the place to start building the Military of the future is in the hundreds of thousands of classrooms. Good thinking once again Tshering.
