- About China and the US cooperating on environmental/climate issues:

 Yesterday I mentioned this detailed and valuable report from the Asia Society and Pew. It turns out that Brookings has just done something similar. Summary here, with links to PDF versions in both English and Chinese. Transcript of event unveiling the report here. I haven't studied the report carefully, but anything in this vein has to be a plus.

- About Mark Bowden and the F-22:

Yesterday I said that I enjoyed Mark Bowden's current article but disagreed with its implied endorsement of the F-22 fighter plane. It turns out that Sam Roggeveen, of the Lowy Institute's "The Interpreter" site in Sydney, has already taken up this topic and gotten a reply from Mark. Roggeveen's initial critique here; Mark Bowden's response here. I should note that, like Roggeveen, I did a double-take at the sentence in the original article saying that at least five other countries were now flying planes that matched or bettered the F-15. For context on that point, it's worth looking here. Also, this Reuters story from three months ago talks about the real-world difficulties in maintaining the "stealth" systems for radar-evasion that are supposed to be one of the F-22's main virtues.
