Wow Code, you really are ignorant.
1) The Arab ("OPEC") nations tried to take over Israel, they lost;
2) The Saudis can't be trusted. They are offering $ to families of suicide bombers, they are home to the bin Laden family, they have manipulated their resources and engaged in price fixing which would otherwise be illegal in the US;
3) No way the Saudis will let us launch any preemptive operations from their country. Hell, they won't even let our female soldiers go off-base without a burka over their head. The only reason the Saudis have let us keep our bases their is to protect their, and Kuwait's, cowardly asses from another invasion.
4) Al-Jezeera, need I say more?
5) Again, you missed the salient points in my argument: We "need" Israel because we have NO other allies in the Mid-East that we can consistantly rely on.
6) What exactly is a Zionist nation? Considering the fact that there are only 13M Jews on the planet, about 7M that live in the US, that would make the US 2% Jewish.
