Urdu was chosen because its has no ethnic color to it. It was a language that could've worked for everyone and it does. Now every Pakistani who has been to school can speak Urdu. Bangladesh's language movement was a political ploy cooked by India to instigate agitation, the people never cared much about Bangla or Urdu. Currency from that time and official documents clearly show that Bangla had official status in both parts of the country. Again the reasons for 71 debacle are political as we should have given the East Pakistan autonomy over its matters except foreign policy, economy and defense. We were lead by men of straw and traitors who had no vision and therefore lead us into an unnecessary civil war.
