Yep, he's a real Janus. His stuff on changing societies is loaded with insight that had a major effect on how people began to think about transformation. The flip-side of his cultural obsession on the foreign policy front is that he really takes culture seriously on the political and economic development front. For all the embracing of Huntington by the anti-POMO crowd, he's in congenial company intellectually with many of the serious "social construction" scholars. He recently teamed up with Peter Berger to edit "Culture Matters" -- on my book pile since Berger's one of my heros and Huntington is always thought provoking. It's a great illustration of how serious scholarship can be hijacked by others for political agendas. (Not that Huntington hasn't helped the process along, mind you.)
