First let's be clear about what he shouldn't do. The United States needs to abandon any illusions that it can transform or find an easy way out of the situation. It is stuck in a region that it can't fix or leave. There isn't a single problem in this region that has a comprehensive or definitive solution. Instead, the U.S. should accept the reality that it will be dealing with outcomes, not happy endings, there. Iraq may never be a unified polity, but it need not necessarily be a failed one.
