Over at the GA blog, they link this (still ongoing) Hugh Hewitt interview series with Tom Barnett. SIx interview sessions, each about 30 minutes of audio. One can learn a lot about the world from Barnett (agree or disagree), though the place of politics and global strategy in the Massketeer menu is a little ambiguous--we are all three of somewhat different views.
I think that the big debate is essentially between Steyn (America Alone) and Barnett (America Unique but Not so Totally Alone as All That). For reference, Barnett is a Catholic-bred, Wisonsin Democrat who voted for Kerry in 04 (according to interview six)--a Democrat (if forced to identify) of the old Hubert Humprey or Scoop Jackson school. I would like to think that Barnett is right, just because he's more optimistic than Steyn, and the world from where I am looks a bit more like Barnett's, but Steyn is a culture warrior and Barnett is a free-market growther.
I link, you decide.
