Put the Tom Clancy clones back on the shelf; this covert-ops chronicle is practically impossible to put down. No thriller writer would dare invent Wilson, a six-feet-four-inch Texas congressman,liberal on social issues but rabidly anti-Communist, a boozer, engaged in serial affairs and wheeler-dealer of consummate skill. Only slightly less improbable is Gust Avrakotos, a blue-collar Greek immigrant who joined the CIA when it was an Ivy League preserve and fought his elitist colleagues almost as ruthlessly as he fought the Soviet Union in the Cold War's waning years. In conjunction with President Zia of Pakistan in the 1980s, Wilson and Arvakotos circumvented most of the barriers to arming the Afghan mujahideen-distance, money, law and internal CIA politics, to name a few. Their coups included getting Israeli-modified Chinese weapons smuggled into Afghanistan, with the Pakistanis turning a blind eye,and the cultivation of a genius-level weapons designer and strategist named Michael Vickers, a key architect of the guerrilla campaign that left the Soviet army stymied. The ultimate weapon in Afghanistan was the portable Stinger anti-aircraft missile, which eliminated the Soviet's Mi-24 helicopter gunships and began the train of events leading to the collapse of the U.S.S.R. and its satellites. A triumph of ruthless ability over scruples, this story has dominated recent history in the form of blowback: many of the men armed by the CIA became the Taliban's murderous enforcers and Osama bin Laden's protectors. Yet superb writing from Crile, a 60 Minutes producer, will keep even the most vigorous critics of this Contra-like affair reading to the end.
