Matthew Yglesias stretches his foreign-policy bona fides:

Mostly, the paranoia of the national security apparatus — represented by the chief of Sector Seven and the guys who want to imprison Bumblebee — versus the correct liberal view that we need to widen the circle of allies, distinguish between good and bad alien robots, etc. Similarly, the Autobots have a minor conflict between the more hawkish Ironhide and the more dovish Optimus Prime on the subject of killing humans, in which Optimus’ more pacifistic stand gets a positive portrayal.

I love big fucking robots.
