Your blame is out of focus. It is Pakistani Muslims in the Sub-Continent who proved themselves unreliable. It was them who betrayed the Pakistan Movement by voting for Congress Party candidates in the 1946 Provinicial election. Now, they say they are anti-Indian.If those BAL supporters are not Indian stooges, that also prove my points again that Bengalis are unreliable partner. They can betray anyone , for anything and at anytime. We don't need anything with Bangladesh.
In 1971, west Pakistan people betrayed those in the east who fought for creating Pakistan more than the present day Pakistanis. After that, they have been propagating against the east for the flip flop.
We are a small country that would survive on flexible mind. You have problem with India and we do not have any real issues except a few imaginary ones. BD should keep on with the good relationship with India.
