If you follow Arab political developments closely, you would have noticed that early on (few months ago), Arab gulf governments indicated that they did not feel any danger or threat from Iran. But when pressured by US, they suddenly felt the danger and the threat. This was like what happened in 2002. If you remember, even the Kuwaiti government then said publicly that it did not feel a threat from Saddam's regime, and that he is contained. But under pressure from US, Kuwait and others suddenly felt the threat. Those government will do anything, will say anything, to appease the US.
