How's that Iraq going?

Mosul’s collapse is Nouri al-Maliki’s fault: Iraq’s prime minister failed to rule inclusively.

This seems like a straight forward explanation of what's going on in Iraq at the moment.  These  paragraphs at the end sum up the bigger picture:

The countries in the region have to form indigenous alliances to stave off these radical threats. The United States can help, but there is no way any American politician
is sending back tens of thousands or hundreds of thousands of troops: They didn’t compel or convince Maliki to adopt a smart policy before, and they wouldn’t be able to do so now.

But this could be yet another sign of a breakdown in the entire Middle East. The war in Syria, which can be seen as a proxy war between the region’s Sunnis and Shiites, is now expanding into Iraq. The violence will intensify, and the neighboring countries will be flooded with refugees (half a million have already fled Mosul), with few resources to house or feed them.

Depending on what happens in the next few weeks, or maybe even days, we may be witnessing the beginning of either a new political order in the region or a drastic surge in the geostrategic swamp and humanitarian disaster that have all too palpably come to define it.

Of course, for some on the Right it's All Obama's Fault.  (I see that John McCain is even taking that line, and I used to think he was a more reasonable Republican.)  But then again, for Tea Party types, if they nick themselves shaving in the morning, I'm sure they curse Obama's name.
