It appears to me that this threat is warning Muslims in Saudi Arabia to stay away from Westerners, where they live and their means of transportation.
They want to disrupt oil operations in Saudi Arabia, and purge the area of any Westerners. They are trying to avoid killing Muslims in the process.
Thank you for the information. We appreciate all input. :)
Agreed. But, they want to hit us on our own soil in the worst way as well.
