India has been pretty successful in developing the Akhand Bharat narrative and ingraining it into Indian minds. At this point, it is irrelevant how silly their media looks to the external audience because the domestic population is naive enough to believe it. Their population has gone beyond the point of where cognitive dissonance would force a reevaluation of beliefs (or perceived reality).
Like one of the guests said, this nonsense propaganda hinders India's foreign interests. But it does not hinder, rather it reinforces, domestic Indian beliefs. Indian narrative is of India a superman and everybody else a boogeyman.
