Iraqi military troops along with Iran-backed Shia militias are fighting to expel ISIS from its two year control of Fallujah. That unfortunate city is also the location of two US battles to "liberate" the city and both times the place was flattened. The US says it is fighting in Iraq to rid the country of ISIS, but is very conflicted over the Iranian role in expelling ISIS. The US government has no strategy to "fix" Iraq, and in fact what it is trying to achieve -- a non-sectarian, unified country not aligned with Iran -- was already achieved by Saddam Hussein before the US "liberation." The only sensible place for the US military to go is home.
