Let Saudi Arabia take care of them. Do they not have a military? It IS in their backyard and all.
Why do WE have to go around fixing everyone’s dammed problems?
The Saudis have a deliberately weak and divided military. If it was as big as their wealth could make it an ambitious general would use the force to topple the Royal House. When the House of Saud feels there is a need for muscle to protect the crown as with the new border wall, the money pours out and what needs to be done is done quickly. Generally the Feringhi are called in to do the work.
