Soon I will write about Sharon's Herzliya speech.
Regarding the rumors of a suicide bomber in New York: of course it's impossible to know if there's anything to the rumor (and let's hope not); and New York is so big that anyone's chance of being in the wrong place at the wrong time are small.
Nonetheless from a purely selfish perspective - here in Israel it's possible to keep relatively safe by avoiding crowds and premises that don't have security guards (assuming you and your family have the luxury of not needing to ride public buses). But you can't avoid crowds in Manhattan.
