Gleiwitz anyone?
I wasn't being entirely serious, but you need to take into consideration that they also hate Iran, so it would be a win-win for Saudi Arabia if this led to war. A couple of Million to fix this mean nothing when you gain Billions.
And as recent events have shown, lots of people in high positions are not exactly smart. Many things I would have considered bad writing in a cheap TV show have actually happened in reality in the past 4 years. We live in strange times.
(It probably was Yemen.)
