I think the Europeans have very little to gain by backing Israel in this conflict..Maybe if some black gold started spurting out in large quantities in Israel they would show more of an interest. Anyhow, the world doesn't revolve around the Jews the last time I checked, (even though I get that impression by the majority of posts/posters on this site) and im sure Europeans have more to worry about than some conflict in the Middle East.
I think the world needs to back Israel right now. Don't look at this as strictly a Jewish thing. These terrorist are using Israel as it's testing ground, terrorism will be more prevalent in Europe and the rest of the world if we reward this kind of behavior. If you believe in a democracy then there is no other choice.
