Kanglus are not going back neither we can make all of them pole vault back into swampdesh. The only thing to do is sterlize all the kanglu women, men and children so they don't breed. These pigs are eating our thin resources which we ourselves are running low. Imagine giving free ration to kanglus food, clothes, medicine, schooling for their little Mujahideens. Huge amount of monetary and resource loss. Our children can't have nutritious food when we have feed all these illegal. Seriously, When I think about these things it pisses me off that general public doesn't give a fuck about these things how actually harmful these kanglus are.The reason the govt is willing to accept 18k people back is because Trump is threatening with tariffs, assuming the news is accurate, I'd prefer some bargaining like you've suggested instead of being the current rollover that this "we take back 18k peepul saar" is.
Bangladesh will reject any official deportations.
Ofcourse, the right way to do this is "incentivize" the Kanglus to pole vault over back to where they came from and never return, but i'll leave it to your imagination what these "incentives" might be
