I don’t understand why are you dragging India into this
If Europe and the US can have ready-to-go antivirals for every possible disease ever then they are encouraged to do that; but realistically for a virus from an Asian reserve it is reasonable to expect the antivirals will be researched and produced in Asia. Can't be ready for everything; and the US should probably be focusing on possible pandemics from Africa where the locals don't have the sort of technical mastery found in Asia.
It isn't reasonable to blame the US government/big pharma for not preemptively curing all possible diseases. It isn't a sensible standard. If they can then they should, but they probably can't. If they can they should be starting in Africa rather than Asia.
