NEW YORK — After a week back, I’ve managed to get some sleep in, say “hey” to a few friends and try to take stock of the aftermath of this war. This is difficult, however, as the urban environment of New York City is so alien to the experiences of the past month that it might as well be a different planet. It doesn’t help that I’m still stepping gingerly around the East Village (residual fear of landmines), looking for sniper positions on the skyscrapers and marvelling that people aren’t all carrying AK-47s.
