Its a well established fact that around 1.5 million people were killed in the 71 war by the pakistani army and its local collaborator razakars. Read what all the well known historian and statistician said about the number of total dead in 71 war.
There's a reason why UN has declared 71 war as one of the deadliest war in the history of mankind where the highest number of civilians were killed in the shortest possible time.
Who told u Bangladesh did not want to punish the Pakistanis for their war crime.
Our biggest mistake was releasing the 93 k Pakistani POWs in 71 war who were involved in killing, looting, raping and vandalizing. Should have prosecuted and hanged every one of them. Anyway, the main reason behind not keeping them captured was perhaps Geneva Convention. Former Pakistan promised to the BD authority and to the combined forces that they would prosecute and punish those 93 k pows which they obviously did not.
It does not really matter whether u believe the actual figure or not. Pakistan was the defeated force and its army committed the heinous of crimes against innocent men, women and children.
Its not surprising that u as a Pakistani find the number of dead people absurd. Indians also denies the allegation of killing and raping kashmiri civilians, Myanmar army also denies the allegation of murdering innocent Rohyanga Muslims, Israel says that it hasn't committed any crime against Palestine civilians. Do these really mean anything?
This is what well known statistician, researcher and political scientist RJ Rummel has said about the mass murder of Pakistani army in 71
"In 1971 the self-appointed President of Pakistan and Commander-in-Chief of the Army, General Agha Mohammed Yahya Khan and his top generals prepared a careful and systematic military, economic, and political operation in East Pakistan (now Bangladesh). They also planned to murder its Bengali intellectual, cultural, and political elite. They also planned to indiscriminately murder hundreds of thousands of its Hindus and drive the rest into India. And they planned to destroy its economic base to insure that it would be subordinate to West Pakistan for at least a generation to come. This despicable and cutthroat plan was outright genocide.
After a well organized military buildup in East Pakistan the military launched its campaign. No more than 267 days later they had succeeded in killing perhaps 1,500,000 people, created 10,000,000 refugees who had fled to India, provoked a war with India, incited a counter-genocide of 150,000 non-Bengalis, and lost East Pakistan"
