Alright this writer is not credible for argument sake but in 1980s when AH was brought from America by Zia and AH organized mamoth rallies in Karachi based on ethinic divide. At that time I was posted at Sukkur Sindh. Zia mardood came to Karachi during one of these rallies and said, "look at me I am also a muhajir so support me". Have you remembered this? He was on TV saying this nonsense.
It is most unfortunate that Paki historians are bikao mall they always praised the dictators and criminals like AH. We never got the true history of any major events in Pakistan. All kinds of lies and nonsense are being taught in the schools under history of Pakistan to new generation, they would never know what actually happened in past so that mistakes should not be repeated in furture.
