The history of the decade begun in September, 2001, has come to a strange and unexpected sort of conclusion today. Waking to history, I was confronted with the death of the most famous enemy of America. The cheers at the death of a human - slightly vulgar - shocked me, but I also felt a curious elation at knowing that Obama had achieved what Bush did not - and some sense of closure. Unfortunately, ripples of violence seem likely - terrorism is complex, despite its seemingly simplistic message. Still, this day, May 2, 2011, is historic.
