Maybe West is advocating a sort of coup to get what needs to be done, done. But rather than an action along the lines of "Diem"; perhaps something along the lines of what happened next door to Iraq is comtemplated.

The Turkish Army took over the country at least twice that I know of in order restore a workable political situation. Then they gave up the power. The question is: Can the American/Iraqi Armies do the same thing?
Short answer: NO

The reason the Turkish Military can do that deal with the traditions of Ataturk and the role of the Military in preserving those traditions. There is no parallel to Ataturk in modern Iraqi history or even Arab history for that matter. And the Iraqi Army has never had the primacy of place in institutions the way the Turkish military has enjoyed.
