Just a pitch to revive this cool thread: Could the comic series DMZ be considered honorary alternate history?
It would be by now - it's only a few years into The Future circa 2005 and the reason for the civil war, "midwestern militia groups revolt against their local governments in protest of rampant U.S. adventurism overseas and, in the absence of the National Guard, are able to gain far more ground than they thought possible", require no major withdrawal from Iraq.
