They left the oilfield workers (like me) alone, but I concur.
I worked in the oil fields as a kid in the summer and worked with a guy who I’ve wondered about all these years. I asked an Uncle recently who knew him too what happened to him. According to my Uncle he went to work in the oilfields in Saudi and was put to death by the Saudis. My Uncle didn’t know why. He was one mean SOB so I suspect he got into a fix that he couldn’t talk his way out of.
