It's really bad. It sends the wrong signal to the world. It looks like submission, not a good signal to send to the Saudis. It's as clueless as Michelle Obama hugging the Queen of England, or George W. Bush giving German Chancellor Andrea Merkel an unsolicited back rub at a summit meeting.
These sock puppets for the oligarchy are all such idiots.
I assert to you that bowing down to another man is not the same as shaking hands. Do you bow down to other men? I don't.
Did any of the other world leaders bow to the Saudi King? no.
Did the Saudi king bow to Obama and show him the same respect? no.
Who bows to the Saudi king? His subjects.
Correction: I have bowed to other men, but that was in martial arts classes, and we bowed to each other simultaneously as equals. I spent 6 months in Saudi Arabia, and I didn't bow to anyone, and no one bowed to me. I shook hands with everybody.
