Iraq's are killing Iraq's.
They aren't killing Americans much anymore.
Maybe the people of Iraq should try working together.
They should, but they never will.
It would be nice if we could divide Iraq into three states, one each for the Shiites, Sunnis, and Kurds, but that wouldn't work either:
Turkey would be pissed off because an independent Kurdistan would cause their own Kurds to agitate for succession, the Shiite south would become an Iranian vassal state (just what we need) with control of the oil and territory that much closer to Israel, and the Sunnis would be pissed off because there isn't any oil in their area, and they'd become just a bunch of poor-assed terrorists, kinda like the Syrians.
