Bangladesh is a failed state. India shud work towards installing a pro-india puppet govt there. That way indians will have a better control over the bangladeshis, their resources and would also B'desh's vote will also count in UN for India claim for permanent Security council seat.

They'll get jobs like toilet cleaner in India. when situation improves in B'desh they themselves will run to bangladesh
