And as I've said elsewhere in this thread, most Bangladeshis are eternally grateful that India intervened when they did.

India's leadership has changed since then, however, and their actions in 1971 do not preclude a subsequent change of heart, or even crass indifference to what goes on downstream (which, honestly, is what I believe is happening now). A robust discussion and much diplomacy is in order between the two countries -- the possibility of which the Indian commentariat in this thread seems to be very eager to shut down.
