Well, it is an old Chapter of the History of Bangladesh and its creation. Indian govt made a grave mistake by making a simple assumption that anti-Pakistan means pro-India. When Bangali Muslims of Pakistan were fighting to upheld the freedom of their country they have named Bangladesh, Awami League was busy formulating ways to subjugate this country to Indian wishes.
This is the reason this treacherous AL is not trusted even today by the BD population. Its every action vis-a-vis India is seen as treason.AL is believed to have a hidden mission, that is, to unite BD with west Bengal in the name of Bangali nationalism. Well, this is a recipe of going back to pre-1947 map, and this is totally unacceptable by us.
