Redeployment

What Murtha called for (not withdrawal):

To immediately redeploy U.S. troops consistent with the safety of U.S. forces.
To create a quick reaction force in the region.
To create an over-the-horizon presence of Marines.
To diplomatically pursue security and stability in Iraq.

Details?

They call for a phased, two-year plan, drawing the troops down to 80,000 by the end of next year and dispensing with most of the rest by the end of 2007. However, they don't call for a total withdrawal. By their plan, all 46,000 members of the Guard and Reserve will go home next year, but most of the active-duty soldiers and Marines will be "redeployed" to Kuwait or Afghanistan. Even after that, many American troops will remain to train, advise, help secure the borders, and provide logistical and air support to the Iraqi regime.

Who Is For It?

Murtha also told Russert, with only slight exaggeration, "There's nobody that talks to people in the Pentagon more than I do."

This is the key point. It is worth noting that most of the leaks about impending troop withdrawals have come from military sources. This is because the military, especially the Army, realizes that the current troop levels cannot be sustained for another year or two without straining the Army's resources to the breaking point—and without quite possibly breaking the Guard and Reserves.
