Because history has shown it. The real question, is it worth the price? Was the partition of India worth some 2 million lives and another couple hundred thoiusand in the seccession of Bangladesh?
The question I was posing is how do you know it wouldn't have been worse if there had been no population exchange?
You don't.
You only can know what DID happen - 2 million innocent civilians did.
There is a reason it's considered a crime.
Where did you get the figure of 2 million from, the best scenario puts the murders of between 10 and 50 million.
10 and 50 million? In the Partition of India and secession of Bangladesh? Estimates vary - upper estimate for the partition is approx 1 million. Upper estimate for the secession of Bangladesh is 3 million (that is considered highly inflated) - I went with an in the middle number of 2 million combined for the partition and later secession of Bangladesh since that was a result of the partition.
In the lead up to partition many millions of Indians were forcibly converted to islam, murdered or ran of their lands. The practise of Suti was brought back by the muslims as a terror tactic when they first raped all the women and then threw them onto fires after murdering their husbands, brothers and fathers. No different to what they had planned for the Jews in 1947, a pity they lost and ended up being shown as cowards.
