Your opinion is greatly appreciated, but many Pakistanis regard him as a hero.
Many White nationalists still regard Hitler as a hero but doesn't make him one. Since you don't watch Pak TV you wouldn't know that most of the militant problems in Pakistan is blamed on Zia ul Haq and Saudi backed wahabi gangs.
Personally i think Gen Mirza Aslam Beg had some idea about Zia's assassination plan, why he didn't travel with Zia even though he was second in command? Could have been work of Al-Zulfiqar- Military wing of PPP to get revenge for the hanging of their leader Zulfiqar Ali Bhutto.
