The conclusion that Musharraf is responsible is too easy. Islam deals in duplicity as a matter of course.
Benazir knew or should have known that, absent massive security, her death was a given; one can only conclude that she had a conscious death-wish.
There had to be teams of killers all the way along the route, awaiting the opportunity to kill her once her motorcade stopped.
As to who set the whole thing up? Irrelevant.
Who finances, shelters, protects and provides intelligence to the killers is the only relevant question.
“one can only conclude that she had a conscious death-wish.”
One can also conclude that Ms. Bhutto lived to satisfy a higher standard than her mere physical existence in this world. She had some ideals and principles which guided her actions. She was not going to be intimidated into a life of fear. She evidently had an understanding with her God and looked beyond this life for happiness and success. May her soul rest in peace and the love of God.
