Washington has little political and no military influence over these developments. As Michael Gordon and Bernard Trainor charge in their ambitious new history of the Iraq war, The Endgame,
Obama's administration sacrificed political influence by failing in
2010 to insist that the results of Iraq’s first proper election be
honored: "When the Obama administration acquiesced in the questionable
judicial opinion that prevented Ayad Allawi's bloc, after it had won the
most seats in 2010, from the first attempt at forming a new government,
it undermined the prospects, however slim, for a compromise that might
have led to a genuinely inclusive and cross-sectarian government."
