When BB wanted to come back to Pakistan, i remember, news papers in Iran reported it with healines like, the first woman PM of Islamic world, a brave eastern leader, a self made woman etc is coming back to her fatherland Pakistan.
Problem was, Musharraf was the strongest political figure of Pakistan and some of analysts warned about challenging his undisputed power by BB. He was the one that threw NS out of Pakistan like a rat into his hole in Saudi Arabia. Hence, Musharraf wasn't someone to easily sideline.
Some accused Mushy, some other accused Zardari but all of those accusations were not backed by solid evidence.
I have no doubt that it was done by Pakistani branch of Taliban which is basically organized and backed by Saudi/USA axis of evil in the region. If we accuse only Taliban or Qaeda, still we are making same mistake. USA and Saudi leaders of terrorists ideology are the main suspects here.
Before elections, i always witnessed some Pakistani politicians raised this issue about lady Bnazir. I guess they do it for political points and i personally believe it is an insult to her memory. Using her for casting votes or provoking emotions of Pakistani people who are deeply bothered with her death.
Even her son Bilawal doesn't dare to introduce people with the main terrorist but he also uses her death in his own favor by shedding crocodile tears in his interviews.
I believe Bnazir was a true and a beloved leader by Pakistanis. Her death threw Pakistan into an endless cycle of political war which opened the way for foreign elements to abuse tge turmoil and make problems for Pakistan and Pakistani people.
