Dude it's common sense if you pull your head out of your ass. Why do we care more about the middle east than something closer, like Canada, or central america? Why do we constantly start wars over there?
For Israel. We don't have any big interests over there. We have enough oil ourselves. South America has tons of oil too. There are very few christians over there. Muslims and jews do not share our ideals, unless you're a necon who considers isreal sacred land. Which is fucking retarded.
