Iraq: The Long War
The military historian Gwynne Dyer summarizes the strategic situation in Iraq. The title is the conclusion -- he foresees a "long" war. He doesn't say what he means by "long"; historically long wars are anything from 8 to 100 years. The current "realist" fashion is to presume an "insurgency"/"civil war" lasting about 5-8 years, then a smoldering "peace" (see Ireland) for perhaps another 20-40 years.
During that time the US forces will be continually stressed and the US will not be able to engage in significant "adventures" elsewhere (much to the relief of North Korea, China, Russia and maybe everyone). Sometime in the next 10 years we will either give up or some administration will start a draft - or hire a very large number of foreign mercenaries. High school students may read about France's Algerian experience, however study of those materials may be considered distasteful, if not seditious.
GWB has established his place in history.
