I feel what's happening in Isreal is a little different then the events that took place in Madrid and Bali. In Isreal you have fighting going on within the country over territory, the people expect and are prepared (as best that can be, I assume) for these events.

What happened in Madrid, Bali, and N.Y. is well planned out mass murder committed by people from a foriegn land who are not willing to share the planet with people who do not share in there cultural beliefs.
