You make a 10,000 Kilometer weapon, USA wont care. It is only hyperbolic hyper sensitive Indians with a inferiority chip on the shoulder who has no idea of of how International politics has to be played on this matter, who talk about this dick measuring contest. Also, Like it or not. USA is a country which was ready to get destroyed itself with an adversary like the Soviet Union, India is nothing to them, currently.
India needs USA for a decade or two. We have much to catch up on.
USA wont jeapordize their important relationship with India, on an issue which they know India will have one day or the other. So why waste diplomatic leverage on it. Unlike silly people on this forum, thankfully diplomats aren't
India will not increase range much over their threat profile, atleast for a decade. Simply, There are other budgetery priorities after threat profile has been addressed. Such as better sub sonic cruise missile's, war head miniaturization, SLBM's etc
There are more technological milestones to achieve before we really break into 10,000+ range, which will take atleast 5 years of R&D
India is not going to make unnecessary ruffles and make life for itself harder, on the ground for its MEA, in the capitals of Europe and Northern America, We have much to get from them. We need to destroy the western centric world order from the inside.
