Nah, that's all wrong.
It's all to do with oil, and how much of it the Americans actually need.
Ergo, Arabs are good.
But Americas military suppliers need the biz, as well.
Ergo Israelis are good, because continual conflict can only generate more income.
Here's where the Americans play their part, wind the Arabs up by supporting the Israeli's for a few years, until the arabs have had enough and threaten oil supplies.
Invade Iraq, because it's spelt nearly the same as Iran and most Americans won't know the difference anyway.
Show fake support for Arab democracy by imposing an unworkable system on them, taking absolutely no account of the realities of in particular Islam or in general the Iraqi's themselves.
Wait 5 years for implosion. Meantime selling weapons to all and sundry in the region.
Wait for Iran to invent nuclear weapon, re-invade Iraq again, because it's spelt nearly the same as Iran, and most Americans won't know the difference anyway.
Repeat cycle for eternity.
