An American Myth Rides Into the Sunset
The image being invoked by the president and his posse has deep roots in the American soil. But if Mr. Bush's cowpoke credentials seem to be all simple syntax and bodacious belt buckle, his policies actually flout the cowboy charter. Teddy Roosevelt, in "The Cattle Country of the Far West," called cowboys "quiet, rather self-contained men." The president's actions have violated the basic terms of the American Western romance and, thereby, the terms by which we call ourselves Americans. He's declared war on a foundational national myth.

It's worth recalling that the cowboy of the myth wasn't trigger happy and he wasn't a dominator. He carried a gun to protect himself and his cattle — cattle that didn't even belong to him. His mission was their safe passage, and by extension, the safe passage of the civilizing society to follow. And his honor was grounded on his civilized refusal to fire first. "Didn't I tell you he'd not shoot?" says a spectator to a gun fight that didn't happen in "The Virginian," Owen Wister's 1902 novel. "He's a brave man," he adds.
