Thomas Stewart says Osama Bin Laden's Al Qaeda is like the Internet. Both are intricate , hard-to-bring-down networks with built-in redundacy. Stewart is a writer who penned the cover story in the most recent issue of Business 2.0 magazine. That story, called "America's Secret Weapon," detailed a new military strategy called "Netwar." Stewart says when you understand how Al Qaeda is like a computer network, you can begin to understand how to attack it.Thomas Stewart writes for Business 2.0, and Fortune, and has written several books on intellectual capital and knowledge management.
