Realize this is a tangent, but it's a followup to my by the way of several posts earlier.
I accessed the article I find interesting, or a version of it. The original is in Foreign Affairs in Jan/Feb 2005 (costs $5.+ to read), I gather, and an adaptation is in October's Harper's readings; it was also in the NYTimes in Feb. Why I should be able to read the NYT article at this point I'm not sure, as one usually has to pay a bit for an old one, even as an email subscriber. (I bet I saved it at the time, and didn't actually read it.)
I like the article as a situational overview. (Surely I am no expert.)
