I disagree with your interpretation. All of Bush’s actions showed mutual respect, admiration, and friendship... A BOW is something COMPLETELY different... COMPLETELY. No ifs, ands, or buts, about it... And, this is definitely NOT “SOP” for the U.S. towards ANY other world leader — EVER.
Bush was also deeply disturbing because it portrayed the despot in a light contrary to how he was seen in the US.
