There is a saying "actions speak louder than words".
Beyond all the rhetoric and nonsense, what is actually happening? Bangladesh is doing business with India because it needs to. We have no other option. This forum and some of the delusional trolls in it have no connection to reality.
Also any modernisation or development of Bangladesh's armed forces is not linked to any offensive posture against India (a nuclear giant) but because we have to be strong and have a strong defensive capability. Our population is bigger than Russia, but we are not seeking to have armed forces bigger than Russia or equal to Russia but still smaller than Russia, but bigger than what we have now, especially given the genodical racist, fascist Myanmar regime next door.
India is a liberal democracy with a strong civil society and nothing like Myanmar.
