December 16, 1971 the Commander of Pakistan forces in East Pakistan surrendered to the Indian Army and Mukti Bahini. East Pakistan became Bangladesh; Pakistani flag was removed from all the buildings in Dhaka cantonment. People of my generation never saw united Pakistan; all we were told about that debacle was a pack of lies through state produced material in shape of text books. It is the biggest tragedy in our national history yet nobody could be held responsible for. It is ever more tragic that the people responsible got state funerals with full military honours. The scale of the tragedy demanded a thorough investigations and publicising of Hamood ur Rehman commission report, but unfortunately that never came. It was only in the year 2000 when this top secret document got published in India. Patriotism demands that the lesson from the tragedy of East Pakistan should be learnt in earnest.  MALIK ATIF MAHMOOD MAJOKA,Australia, December 10.
