Permanent Bases Again?

Seriously, I thought this was done. The New York Times has this errant mention, though:

Even if the goal of withdrawing combat troops by 2011 is realized, the accord does leave open the possibility that American military trainers and support forces could remain in Iraq after that time. It is unclear whether the accord provides for semipermanent military bases in the country, and what role the United States would play in providing air and naval support for Iraq.
