Correct, during my brief tenure in the ME you could sense the fear from all the little sheikdoms whenever the Iranians would demonstrate in any way. Their stated goal is take over of the STRAITS OF HORMOUZ and shut out everyone elses oil export. If ISIS or likely Al Qieda makes a concerted effort to control the country this would be Iran's excuse in order to "protect" mecca...the real goal is control of the oil fields and the Straits.

Now normally this would not be an issue with the US  protecting the Saudi's but this clown in the WH you never know what he would do or allow.
