When I was a professor at FIU in Miami they stuck me with 180 Saudi students for one quarter. These guys were going to be the Saudi royal guards and many were part of the royal family. They lie and cheat on a daily basis. It’s an acceptable part of their culture. They do it with a sweet smile on their face. Always remember they do not subscribe to the judeo Christian ethic. They are muslims. King Salmon likely lied to Trump’s face.
I had on fellow student who got a kick out of going into the room before the exam and cleaned the Arabic writing off the desktops in the back of the room. There were some angry Arabs those days.
