Thanks for the Center for American Progress' Progress Report, here's a little item from NPR about how the Pentagon is planning for a "decades"-long stay in Iraq:

The Pentagon has not published any contingency plans on how to deal with Iraq in the event of a large-scale drawdown, but it is discussing various scenarios.

A series of military installations could be maintained around Iraq, with a total of total of 30,000 to 40,000 U.S. troops, for a long period of time — maybe a few decades. There are currently about 160,000 U.S. troops in Iraq.

The bases would be located in various strategic locations, ones that served by air landing strips, for instance. The bases would be sealed and U.S. forces wouldn't be on patrols as they are now.

Meanwhile, the Washington Times reports that Iraqis are developing contingency plans for a quick pullout:

Iraq's military is drawing up plans on how to cope if U.S.-led forces leave the country quickly, the defense minister said yesterday.

The statement by Defense Minister Abdul-Qader al-Obeidi marked the first time a senior Iraqi official has spoken publicly about the possibility of a quick end to the U.S.-led mission.

It was not clear whether the remarks reflected anything more than routine contingency planning. "The army plans on the basis of a worst-case scenario so as not to allow any security vacuum," Mr. al-Obeidi said. "There are meetings with political leaders on how we can deal with a sudden pullout."
