Israeli Intelligence warned us of this attack before it happened. If they chose to warn their own people it only shows good sense on their part. I only wish our Intelligence Community had taken their warning so seriously.
There was not 4,000 Israelis working at the WTC. If there was, there would have been a very large amount of Israeli companies as tenants which there aren't.
Somone could say that one company might employ 4,000 employees but the day of office workers sitting shoulder to shoulder are over.
