Well wether Awami league was allowed to made Govt. or not, but there were enough things done by West for East to become a separate country. We tried to kill their mother language by imposing Urdu on them and left only jobs like peon for them in the Govt offices. The thing is if we have treated East better, things would have been different by now.
Urdu was not a west Pakistani language, nor was it an East Pakistani one. It was the language of hapless migrants, U.Pites that travelled to the West, and Biharis to the East.
Incidentally, it was also the language of the later Mughal rulers of India, as well as the adminstrative language the British used in Northern India.
It was the only language that could have been the official language, as no one province could claim it, and lord it over others. If Bangali or PUnjabi had been the official language, the partition of Pakistan would have been much sooner.
The Bangali language is a rich and respected language, yet so too PUnjabi, Sindhi, Pashto, Baluchi, Kohistani, Balti, Siraiki, Hindko, and others. To give the Bangali language the status argued for, would have done exactly that to members of other linguistic groups, which the Bangalis themselves complained about.
As for government jobs for Bengalis, then it must be known that Bengal had more educated people than West Pakistan, Bengal in Bharat is also traditionally more literate than the rest of Bharat. For this reason, East Pakistanis regularly topped Civil service and Public service examinations, giving them many high posts in West and East Pakistan. Trust me, they were anything but peons.
Sheikh Mujib's six points were in essence, a decleration of seperation and division of Pakistan, or at least perceived so by many. I guess there was a trust deficit, and the West Pakistani politicians did not trust Sheikh Mujib not to go through with it.
We as Pakistanis, might sometimes by nostalgic and sad about what happened, yet in no way are we bitter, nor do we begrudge our Bangladeshi brothers their homeland. Yet do not be upset if we take a keen interest in your affairs, it is only due to brotherly concern and shared memories.
It should be noted though, that Providence has not been kind to the three architects of the division of Pakistan. The violent deaths of Z.Bhutto, I.Gandhi, and S.Mujib might have a lesson in them for us.
