Okay, the past several hours have resulted in a deluge of information regarding bows by US Presidents to not only foreign leaders and personalities. I mention just two of them that are making the rounds: Prsident Eisenhower bowing to the President of France Charles DeGualle in 1959 after a speech given by DeGualle, and President Nixon bowing (get this) to the Emperor of Japan Hirohito (the very Japanese Emperor who presided over the attack on Pearl Harbor) while on American soil (Alaska).
