The US and Israel are aware of a possible security arrangement in the Gulf between Iran and the Arabs and there is nothing more they both fear of happening.
To make such an arrangement impossible, the US and Israel are concentrating their efforts in spreading sectarian violence in the region between Shia and Sunnis (as in Iraq and Lebanon). Not surprisingly did the King of Jordan start to talk last year about the "threat of a Shia Crescent" and the president of Egypt accused Lebanese Shia to be Loyal to Iran and not Lebanon.
The US and Israel are in search for another Saddam in the region who can be used as a puppet and counter Iran militarily.
It is not in our (Arabs) interest to confront Iran and be a hostile neighbor to it. American and Israeli hegemony in the region is far more dangerous than Iran's nuclear ambitions. I wish Arab leaders would start to uphold the interests of their people instead of their own narrow interests.
