Although i am a pro nawaz person, but trust me Bhutto was the best leaders we had after Quaid-e-Azam. He was very daring, and only one of the few leaders who could see America, eye to eye.
He was killed, because of his great plans to unite the muslims of the world. He was not a Maulvi in the traditional sense, but he had done a lot for Islam in pakistan. Pakistan owes its nuclear assets to bhutto's vision. He got the money from Saudi, Libiya and named it Islamic bomb.
American's threatened him that if you go on with making the bomb, we will make a terrible example out of you. He ignored, and went on with his decision.
I think he was an excellent leader.
