“Any time Uncle Sam, with all his machinery for warfare, is held to a draw by some rice eaters, he’s lost the battle. He had to sign a truce. America’s not supposed to sign a truce. She’s supposed to be bad. But she’s not bad any more. She’s bad as long as she can use her hydrogen bomb, but she can’t use hers for fear Russia might use hers. Russia can’t use hers, for fear that Sam might use his. So, both of them are weapon-less. They can’t use the weapon because each’s weapon nullifies the other’s. So the only place where action can take place is on the ground. And the white man can’t win another war fighting on the ground. Those days are over. The black man knows it, the brown man knows it, the red man knows it, and the yellow man knows it. So they engage him in guerrilla warfare. That’s not his style. You’ve got to have heart to be a guerrilla warrior, and he hasn’t got any heart.”
