"I think if we were to do what Speaker Pelosi and Congressman Murtha are suggesting, all we'll do is validate the al Qaeda strategy," Cheney told ABC News.
"The al Qaeda strategy is to break the will of the American people, knowing they can't win in a stand-up fight, try to convince us to throw in the towel and come home and then they win because we quit," he said.
"I think that is exactly the wrong course to go on," Cheney said. "I think that is the course of action that Speaker Pelosi and Jack Murtha support. I think it would be a mistake for the country."
