I do not remember seeing any picture of President Bush bowing to Saud. I would be intereted in seeing it if Mr. Newt or anyone can find one. He did hold hands with him.
I googled “bush”, “bowed” and “saudi” and got this:
Bush did NOT bow before the Saudi king in this; he bent over so the king could place a necklace around his neck the way I’ve done when I’ve gone to Hawaii and had a lei placed around my neck.
Bush kissed him on the cheek, NOT the hand - which is merely a sign of loving respect - and NOT fealty. He has also (not in this vid) held the king’s hand - but again, Arab men hold one anothers’ hands as a sign of friendship.
Based on what I saw in that vid, the “bow” claim is a lie.
I was wrong about Bush, he lowered his head to have some kind of medal put around his neck. That hand-holding was pretty creepy, though.
