With your obsession about Gulf Arabs, have you ever been to one? Indians are on the lowest rung of society there, below even Africans. They do the worst jobs.India may not independently develop these systems but India sure will have ability to maintain them like Boeing Aircraft or some of the vessels or helicopters like Chinook/Apache/Airbus helicopter. or information systems. India is now among the largest non EU students in Germany. and practically No 1 in English speaking world. It is like take over of existing structures in next generation. These Gulf Arabs have strategic outlook and they do hire alot of foreign staff. It is all about managing infrastructure /people and make your country not only wealthy but attractive in Soft power that people work for you.
holding hand together they will manage Africa
The Gulf states have contracts with Boeing, Airbus etc for maintenance. Why would they forgo that to depend on a country that can't maintain anything, let alone foreign military platforms? You are delusional.
