so, is the cfr a better or worse source than the atlantic? i don't know. that's a pretty daunting insult directed at the atlantic...
if this is the way things are, that is good, as it's also how things ought to be.
again: there's ways to sort of try to blunt the effects on bangladesh by trying to scatter them around a little - to pakistan, to the middle east and, in some small numbers, perhaps to canada, as well.
but, that line was drawn to give the buddhists in the former empire a homeland of their own, and the muslims don't get to encroach on it just because they overbred. they don't get lebensraum by default, just because they're muslims, or because they're brown.
they need to get their population levels under control, not argue that overpopulation gives them some kind of right to spill over into neighbouring regions. and, whatever the solution to easing the existing issues are, they should come with the acceptance that the country was partitioned for a reason, and muslims need to stay out of the buddhist regions.
....at least for now. we don't talk like that on this side of the world, but it's because we've reached a different cultural plateau. and, some level of atheism in the region, an inevitable consequence of higher standards of living, is likely the way to get to a more substantive level of peace.
for now, these religious groups don't like each other, and their various autonomy needs to be respected.
i'd say the same thing if you flipped the situation over.
