Arab populous doesn't have much leverage though, while Arab regime does...palace it is and palace is what opposes a nuclear Iran. Quietly, most Arab regimes will support a strike on Iran.
You are absolutely right in that arabs don't have as much leverage as their government. They never did and never will. However, ask any ordinary arab on the street how they feel about allie's occupation in Iraq, expansion of illegal settlers in WB, etc, et, etc... and you are there for a surprise contrary to the popular belief. Nevermind shia and sunni divide as some here claim as the contentious issue. Both sects have been living side by side for centuries and sure there has been conflicts. I don't see how such religious conflicts concerns US or the west for that matter. Religious divides and conflicts even exists between protestants and catholics to date. (Northern Ireland)
It's indeed the arab palaces that are puppets of the US and are used as a bargaining chip. Any major opposition to the US policy in the ME and the US policy makers can turn the tap off on their military aid, what comes out of the horse's mouth and even the sheik's own survival as the ruler of his country.
