U.S. Defense Secretary Donald Rumsfeld said on Sunday that American forces would not defeat Iraq's rebels but would make way for Iraqis to put down an insurgency that could go on for a decade or more. "That insurgency can go on for any number of years," Rumsfeld told Fox News, according to Reuters. "Insurgencies tend to go on five, six, eight, 10, 12 years. Foreign forces are not going to repress that insurgency. "We're going to create an environment that the Iraqi people and the Iraqi security forces can win against that insurgency."
