People talk about having or buying all these "stealth" platforms, countries dream of it. But the real question is, even if u get it, what is it for? What are the usual ongoing maintenance and upkeep costs to keep them running and flying. Will they stand all day during peacetime gathering rust ??
There is a huge cost to them, and if any maintenance is required, there will be huge contracts and payments to the OEM manufacturer who will do it and they won't let locals do it. A VERY VERY EXPENSIVE white elephant to have and keep. For a battle of few mins/hours? A decent AF can do pretty much same with other integrated stuff like what the PAF did. It seems an overkill at this time.
If they (usa) want to force india to "waste" its money (and empty its coffers into this endless money pit), we should be glad as it will tank their economy. Those americans will dry them in no time with even 1 squadron and pretty sure no "source-codes" will ever be given. India as a belligerent extremist nation will want to test them to destroy Pakistan when they get it, and leading to another war.......does the US want that again? Sure destroy the region then, create WW3.
The west in general (us and eu) is in decline, stagnant economies, filled with immigrants, loss of employments and shit life standards in general, is happening. Even worse is the rot in the population due to uber fast food gobbling, becoming obese gamers and social media psychos and mental health sufferers. Anxiety, Depression, and broken family system has already messed them up, covid19 further destroyed their societies. One more extreme push/shove and they collapse. So the only thing is left is to go gather money from those who still have some left. India is a poor country in itself and if it loses its "billions" to usa with all this shopping, so be it. The usa did it with the arabs recently with getting trillions from them already.
It won't end well for anyone to think that wars/conflicts won't spread.....once the flashpoints ignite, it may be a chain reaction and will consume everyone. Specially when restraints are off the next time and escalation is immediate.
PAF with its current J10C and JF17-B3 doesn't have much to worry about for a long while as the indians are just incompetent and stupid. They will always be afraid and wary of Pakistan now (militarily). If they thought that Pak was a weak state militarily and in defense, they got a rude awakening. India is on its way to implosion from within whether they like it or not, due to their own shit internal and external policies of the hindutva/rss/moditva etc
