Except that it was stable when Bush left office, as Peters points out. It wasn’t Bush’s fault that Obama didn’t negotiate a SOFA. If Bush had had a responsible successor, things could have turned out very differently.
Why would Obama negotiate a SOFA if Bush had already negotiated one that laid out explicit terms for the withdrawal of U.S. military personnel from Iraq after Bush left office?
Iraq became FUBAR once the Bush Admin. pushed the convoluted pro-Islamic Constitution there. BTW, “political expediency” without regard to being able to readjust the direction yourself is called incompetence, not strategy.
