The important thing is developing the entire supply and production chain so you are self reliant and sufficient.
I can see India's uneasiness and jealousy since they are bound to the usury projects with Russia on the T50 (Russia is not going to let India have the real thing) and the Nuke Sub's (India will be lucky getting a foot long Subway sandwich with half of the trimmings out of it. It's already dealing with humongous cost overruns).
Why would anyone put in their hard earned money and partner with Russia? They already failed at the USSR project. Why wasting prescious time just go full steam ahead with the US and serve Uncle Sam the way India served the British Empire?
That is the typical Indian paradox.
