at a very first glance,one can easily locate the flaws that leaded towards the fall of dhaka.as we all are aware of this very fact that after partition the bulk of the ruling class including prime minister,president even the speakers of national assembly and coas as well were elected from the west PAKISTAN and consequently that ruling class shown immense descrimination towards the natives of east PAKISTAN.and the point to be pondered is that at the time of partition the east PAKISTAN was enormously rich in resources as compared to that of the west PAKISTAN but unfortunately east PAKISTAN was not awarded the full value of what it had.eventually that sad event took place.
along with all these facts,to be very pregmatic east PAKISTAN hasd not any firm strategic connection with the west PAKISTAN but the blood connection only.
i have portrayed the extremely short picture of that event.
