Bush's illegal war has disturbed the Mid East regions Snni/Shia balance, by installing a Shia government in Iraq. KSA now funds Sunni insurgents in Iraq to balance the US backed Shia Iraqi regime. Dubai has stated they will not let Bush use the brand new Air base in Dubai to attack Iran.
Israel is fighting Iranian Shia funded fighters, this could align Israel with KSA. UAE is a major oil producer with many shared petro projects with KSA.
No one in the ME region wants more war, attacking Iran could enflame the entire ME region, if that happens, all bets are off, things very likely would spin out of control.
I believe that when the 15 British sailors were nabbed by Iran, many players in the ME region decided it was time to get proactive, and take charge of events in the region. Bush told Blair that US jets could push at the edges of Iranian airspace, at the time, IIRC we had 2 carrier groups in the Persian Gulf, which is actually rare to have 2 carrier groups in the Gulf at the same time. Blair told Bush to remove the carriers from the region, basically to mind his own business.
Simply put KSA UAE & the Bush Crime family are the evil triumvirate. KSA has bought new missiles from Pakistan, capable of delivering nuclear weapons.
