I think he was doing well until he got heavily involved in politics and with the Chaudharys.
Just look at his economic policies, although Shaukat Aziz might have a bit of a hand in that.
He messed up with the constitutional framework of the country though and that was the thing that agitated the political parties, who in turn got support from the masses through the free media.
No mate we needed someone who had the masses with him. Can you imagine if he had exterminated lets say 1000 to 2000 in Pakistan all the corrupt parasites and their families. The people would have been with him, he shouldnt have entertained any of those political leaders.
