Having said that, I wouldn't go to Saudi Arabia for a million dollars. It's not racist to point out the shortcomings of a national culture. Name one piece of technology used in this attack that was invented or even built in Saudi Arabia. Name one program that was written there. If you can't, it's not my fault. And clearly they're not so oppressed by Israel and the West that they can't afford to buy nice things, or build their own industries if they choose to. I know Lebanese guys who've moved back to Beirut to do startups. Look at Qatar and Dubai. They're too busy branching out and moving beyond an oil economy to be envious of middle-class Israelis.
It's also not racist to point out the lack of character involved in attacking civilians in another country, allegedly in protest of a foreign government, while you yourself live in a phony, sham-theocratic dictatorship.
If anything, I think it's people like yourself with your "good intentions" of pointing out who-must-be-a-racist, without deigning to criticize the giant racist elephant in the room, who are mostly responsible for the continuation of problems in the ME. To quote a famous Christian, first take the plank out of your own eye.
