Notice the use of the word "concepts": "The Bush administration is developing what are described as concepts for reducing American combat forces in Iraq by as much as half next year, according to senior administration officials in the midst of the internal debate. It is the first indication that growing political pressure is forcing the White House to turn its attention to what happens after the current troop increase runs its course. The concepts call for a reduction in forces that could lower troop levels to roughly 100,000 by the midst of the 2008 presidential election, and they would also greatly scale back the mission that President Bush set for the American military when he ordered it in January to win back control of Baghdad and Anbar Province."
