The Saudí monarchy is to ISIS as Dr. Frankenstien is to its monster. It created to fundamentalist movements, but has lost control. Like Frankenstien, ISIS will return to kill its maker. The monarchy is not popular. ISIS is very popular among non royal Saudis. The largest number of twitter tweets of support are coming from Saudí Arabia. The monarchy can quickly find that the ground has shifted underneath its feet.
That is a great description. I think you nailed it.
