Clues to new breakthrough in modern weaponry and warfare

The program — which Woodward compares to the World War II era Manhattan Project that developed the atomic bomb — must remain secret for now or it would "get people killed," Woodward said Monday on CNN’s Larry King Live.

"The top secret operations will "some day in history … be described to people’s amazement," Woodward told King.

While he would not reveal the details, Woodward said the terrorists who have been targeted were already aware of the capabilities.

"The enemy has a heads up because they’ve been getting wiped out and a lot of them have been killed," he said. "It’s not news to them."
