Al Qaeda has evolved and adapted, and has committed more terrorist actions since September 11 than it did before. President Bush's "War on Terror" has not been successful. That's according to a study by the RAND Corporation, which has analyzed strategies against terrorist groups from 1968 to 2006. The prestigious Defense Department contractor says there's a better way. Although "intelligence and local police work" is a lot less politically sexy, RAND says it has worked where military action has failed. Is it time to rethink US strategy? In the age of nuclear weapons, is there a third way?
