I imagine you've already seen this Washington Post article outlining a pentagon summary of options in Iraq but just in case you missed it-
Pentagon review sees 3 options in Iraq
The Pentagon's closely guarded review of how to improve the situation in Iraq has outlined three basic options: Send in more troops, shrink the force but stay longer, or pull out, according to senior defense officials.
Insiders have dubbed the options "Go Big," "Go Long" and "Go Home." The group conducting the review is likely to recommend a combination of a small, short-term increase in U.S. troops and a long-term commitment to stepped-up training and advising of Iraqi forces, the officials said.
Personally I would haved dubbed the three options "Go Big," "Dogpaddle" and "Go Home" but that's just me being a silly realist. "Go Long" does imply throwing a Hail Mary pass so at least it somewhat captures the slim chance of success of what really amounts to staying the course.
