Not Going Anywhere For Awhile?

According to Army chief of staff, Gen. Peter J. Schoomaker, neither is the U.S. Army. Schoomaker says we're going to have troops in Iraq through 2010.

So, we've got 141,000 troops in Iraq, including 120,000 Army soldiers. The Pentagon has had to extend the Iraq deployments of two brigades in order to try and maintain security in Baghdad.
We're having to rely on the National Guard and Reserves just to maintain the current level of deployments. The U.S. military death toll in Iraq has risen to at least 2,750 since the war’s start in March 2003. And Schoomaker says the Army will need $138.8 billion in 2008, nearly $40 billion more than its planned expenditures for the 2007 budget year, which began Oct. 1.

All this for what again?
