If you lived in a community outside of the US comprised of people who had given up on their country you would hear about a coming civil war here as well.
I don't see how anyone can generalize in good faith from one unprecedented attack to a condemnation of the hundreds of thousands of Jews who live peacefully in the West Bank and Gaza. Moreover, we don't even know the facts of the attack yet. It may turn out to be something different from what you are assuming.
I have a feeling that I am about to take a bit of a massive sh*t sandwich by weighing in on this, but it seems to me that one of the primary causes of ridiculous violent behavior is idleness. We see it in the Arabs who have nothing to do but sit around in the sand, and we see it in gangs in the inner city who have nothing to do but sit around all day.
Isreal's subsidizing the radicals who don't work, but rather sit around all day with their pals in the religious schools is going to come back to haunt them.
People who have to work, take care of kids, make food, etc. don't have time to fill their heads with crazy thoughts, and also understand better the consequences of their actions.
One crazy man doesn't mean anything, unless of course you think Tim McVeigh represents all Americans or Christians...
