The whole U.N./U.S./U.K. war fiasco is looking increasingly like a U-circus — which is somehow alluded to in this week’s New Yorker. No, not in the actual content of the magazine but in the first 10 pages of ads by clothiers like Banana Republic, Prada, and Armani. I’m sure it’s not my imagination getting the better of me — in the ads, tents and clowns and colorful text and fanciful textures are all a play on the carnivalesque that is our daily political and economic environs.
