Osama bin Laden began his life as the son of a contractor made fabulously wealthy by the Saudi Arabian oil boom. From an early age, bin Laden shows himself to be different from his Western-leaning family. He forges a close relationship with the radical preacher Abdullah Azzam, who he joins as a mujahideen fighter in the Afghan War. Bin Laden will eventually be lionized by some in the Muslim world as the man who gave up the comforts of his upbringing to risk his life in battle -- and steered a share of his family wealth toward the cause. Once the invading Soviets leave Afghanistan in defeat, bin Laden decides to fight a holy war against the West. But how? His longtime mentor, Abdullah Azzam, advises caution. But a new advisor named Ayman al-Zawahiri pushes bin Laden to pursue a more far-reaching strategy. Bin Laden’s choice between the two men will determine the path of the newly formed Al Qaeda, and of worldwide militant jihad.
