Tom Clancy, bestselling author of such military thrillers as The Hunt For Red October and Patriot Games, is being treated like an actual terrorism expert, having offered his opinion on Larry King Live and countless other TV shows since Sept. 11. 'The Al Qaeda network is known to have operatives in at least 30 countries, including the U.S. and Great Britain,' said Clancy, a former insurance broker and avid wearer of naval-warship baseball caps, during a recent Nightline. 'By the way, Ted, Stephen Ambrose's The Wild Blue is a terrific read.' Later that evening, Clancy appeared in a Crossfire panel on biological warfare with former CIA director John Deutch and Secretary Of State Colin Powell.
