LOOOOOOOOOOOOOOOOOOOOOOOOOOLz 
why did people of East Pakistan rise up?
please answer that…
was it because that a cyclone killed 500,000 bengalis and we did nothing?
was it because that they had a majority population and we didnt abide by democratic principles allowing a bengali to become PM of Pakistan?
was it because of our racist treatment towards bengalis?
was it because of the lack of development that went to East Pakistan?
