The only part of the Berlin Biennale that remained in my mind well after making the obligatory rounds was the inclusion of the text of diplomat John Brady Kiesling’s http://truthout.org/cgi-bin/artman/exec/view.cgi?archive=1&num=61">resignation letter in an otherwise unremarkable installation based around a 1997 missile attack on the US embassy in Athens. It’s a sad state of affairs when the most memorable part of a high-profile art exhibition was penned by a career bureaucrat, sadder still when those words contain an unmitigated gravity that only grows by the day.
