Beyond that, New York City has the largest population of Jews outside of Israel. NYC is THE most "Jewish" American city.
And beyond THAT, I can't think of any cultural symbols they could have attacked in Israel that wouldn't have killed many of their own people and destroyed some their OWN most cherished icons.
I've kept my eyes open for just that, but so far haven't seen one.
My specific interest would me more on the line of "Position" in their Office/Company along with Ethnicity of those who died.
