I would point to yourself before you point to another. India simply did what's in her interests....it would simply not have worked if BD asserts its own identity and interests with enough force through its own people (if they are indeed in much contrast to India). Simply making India as be all end all bogeyman, just continues the problem within BD.
And we will not see much if any pain from BD (only bad one somewhat I can see are the illegals situation)...still very worth what we attempted and succeeded in. Pew survey still finds largely favourable attitude in BD to India. The consumption of say Indian bajaj motorcycles (to near exclusive nature) and 1+ million BD tourists (often medical related) to India each year now paints quite the picture on the ground.
Seriously just few donations of memorabilia from 1971 war and so many of you prostrate in thanks....that is a nature you lot have to change, not us.
