I lived in the Muslim world for 10 years.

If you put your politicians up for sale, as the US does (alone in this among industrialized democracies), then someone will buy them--and it won’t be you you can’t afford them.

Partisan politics has no place in the classroom.

I also argued before the war that the administration was underestimating Arab nationalism and Iraqi nationalism, that it was not going to be as easy to rule Iraq as they thought.

To the extent that the (ISIS's) advance is a series of urban revolts against the government of PM Nouri al-Maliki, the US would end up bombing ordinary city folk. For the US to be bombing Sunni towns all these years later on behalf of Mr. al-Maliki would be to invite terrorism against the US.

Did you know that they introduced the 15 percent flat tax on individual and corporate income in Iraq? Something that some politicians very much wanted to push in the United States without success but in Iraq they do it.

My main expertise is in the past, but if I have to extrapolate into the future, I would say: no good news any time soon and an obvious exit strategy is not apparent to me.

I argued that the Bush administration, and the Coalition officials more recently, didn't understand Iraqi society. They thought it was a blank slate, that they could use Iraqis as guinea pigs.

I think that there's been an unfortunate tendency for right wing think tanks to dominate these discussions. They often produce very shoddy studies and policy recommendations, which are nevertheless taken very seriously.

An occupying power has no right to make significant alterations in the character of the occupied society, to change the laws all around, without a strong security reason and so forth.
