So there are plenty of ingenious minds out there that are at work finding ways in which they can wreak terror upon other nations...It's real, and that's the reason why we have to intensify our [counterterrorism] efforts."
-- Secretary of Defense William Cohen at an April 1997 counterterrorism conference sponsored by former Senator Sam Nunn.
