Excerpt from Bin Laden by Yossef Bodansky, plus links to reviews, author biography & more

NOW IN HIS MID-FORTIES, a university graduate with computer skills, Osama bin Laden lives with his four wives and some fifteen children in a small cave in eastern Afghanistan. They have no running water and only a rudimentary heating system against the extreme cold of winter. Bin Laden is always on guard against assassins, commando raids, and air strikes. Had he followed the path chosen for him by his father, bin Laden could have been a respected building contractor in Saudi Arabia and a billionaire in his own right. Instead he freely elected to abandon the life of affluence and commit himself to waging a jihad under extremely harsh conditions.

Osama bin Laden is not the only Islamist who has abandoned a good career and comfortable lifestyle in order to wage a jihad. Dr. Ayman al-Zawahiri -- bin Laden's right-hand man -- now in his late forties, could have been one of Egypt's leading pediatricians but gave up a promising career and affluence to fight the Egyptian government. He then refused political asylum in Western Europe (with a generous stipend) and ended up living in eastern Afghanistan not far from bin Laden.

Although bin Laden and Zawahiri are the most notorious Islamist terrorists, there are hundreds like them. These dedicated commanders in turn lead thousands of terrorists in a relentless and uncompromising holy war against the United States and the West as a whole. The bombings of the U.S. embassies in Kenya and Tanzania in 1998 were the latest but by far not the last shots in this rapidly escalating war of terrorism. What makes these individuals -- the leaders and symbols of the new Islamist upsurge -- commit themselves to this kind of war?

The rise of the new radical Islamist elite is a recent phenomenon in the developing world. These leaders, from the affluent and privileged segment of society, are highly educated and relatively Westernized. They are not the underprivileged, impoverished, and embittered isolates who usually constitute the pool that breeds terrorists and radicals. These Islamist terrorist leaders are different from the typical European middle-class revolutionaries and terrorists -- from the anarchists of the nineteenth century to the Communist revolutionaries of the late twentieth century -- because the Islamists have become popular leaders of the underprivileged masses, while the European terrorists remained isolated from a generally hostile population. Only Ernesto "Che" Guevara -- the Argentinian doctor turned revolutionary fighter of the early 1960s -- came close to being the kind of populist leader these Islamists are.

To understand these Islamist leaders -- particularly Osama bin Laden -- one needs to understand their break with their past, their motivation, the fire in their veins, and the depth of their hatred of the United States and what it stands for.

OSAMA BIN LADEN, Ayman al-Zawahiri, and their compatriots, mostly Saudis and Egyptians, are the product of the tumultuous 1970s and 1980s. Their entire lives, from their early years up until the time they rejected a luxurious lifestyle and embraced radicalism and militancy, were strongly influenced by key events unfolding in the Middle East -- most importantly, the Arab prosperity and identity crisis that accompanied the oil boom in the 1970s, the triumph of revolutionary Islam in Iran, and the rallying cry of the jihad in Afghanistan in the 1980s.

Osama bin Muhammad bin Laden was born in the city of Riyadh, Saudi Arabia, probably in 1957. At the time his father, Muhammad bin Laden, was a small-time builder and contractor who had arrived from Yemen in search of employment. Osama was one of numerous siblings -- his father had more than fifty children from several wives. Muhammad bin Laden was conscientious about education and advancement in life and tried to provide his children with proper schooling. During the 1960s the family moved to the Hijaz, western Saudi Arabia, and ultimately settled in Al-Medina Al-Munawwara. Osama received most of his formal education in the schools of Medina and later Jedda, Saudi Arabia's main commercial port on the Red Sea.
