Yeah right, if Bangladeshis didn't want independence in 1971, the mighty supa pawa India would have just handed it over to us in a platter by fighting Pakistan on both wings. Keep dreaming.
We got independence, because we wanted it and fought for it. You helped because it was to your benefit. You didn't do it for charity.
Instead you tried your very best to destabilize Bangladesh after liberation by funding, arming and training the Chittagong Hill Tract separatists.

So get off your righteous horse and stop making a fool out of yourself.
They want bangladeshis to live like dogs - always grateful for something they did to help themselves.
