Fought between 1979 and 1989, the Soviet-Afghan War provided vital combat experience for Osama bin Laden and his senior lieutenants in al-Qaeda, allowing them to hone their newly acquired skills in guerrilla warfare to later support Islamist insurgencies worldwide. Yet the ruthless al-Qaeda chief's success depended on the Soviet leadership's reluctant prolonging of its military occupation out of fear of leaving Afghanistan in hostile hands. As relative latecomers to the ferocious Afghan frontlines, the inexperienced Arab fighters benefitted militarily from the combat training unwittingly provided by their Soviet foes. After skillfully obtaining this command and battle experience by working within the wartime atmosphere, bin Laden channeled al-Qaeda's efforts in a global jihadi campaign targeting a second superpower and its allies. While allegations of U.S. support for the Arab jihadis have contributed to a popular image of bin Laden and al-Qaeda as C.I.A. creations, the historical facts appear to demonstrate that the combat opportunities provided by the Soviet occupation forces played a far larger role in transforming them into seasoned guerrilla fighters. In this second edition, Reagan Fancher updates and expands his monograph in an Afterword elaborating on the contemporary U.S.-U.K. perceptions of bin Laden's wartime actions and their results as he applied his battle-honed guerrilla tactics, judo skills, and recruitment capabilities in tactically helping Yemen's anti-communist Salafi guerrillas to emerge victoriously in their country's 1994 Civil War before concluding with an assessment of the founding al-Qaeda leader's impact on history. It offers an opportunity for today's decision-makers to learn from history and avoid creating new generations of Osama bin Ladens.
