If he had 66 service ribbons, where would he put them? Even if he put them on both sides, there still wouldn't be room. I think the USAF has around 84 possible medals/ribbons but to obtain that many you would have to have been a participant in every conflict that existed from WWII until present time which encompasses 80 years of service ( so who was handing out participation trophies like they are candy?) I was in involved in almost every conflict from the Iran/Iraq (late 80's) war/Cold war through OEF/OIF and ended up with 23 medals/ribbons and umpteen hundred combat flight hours. There was barely enough room on the left side of my chest to accommodate those and my wings but you wear them because you earned them ( do you know how much easier it is to just line up two or three ribbons? More than one row is no picnic). When wearing Mess Dress only actual medals are allowed and still I looked like a mid-East dictator (even minus the "you lasted 4 years without being a total F-up" and "wow you made it through basic training" or "congrats you endured 3 or 4 years of service" ribbons). It is looked at as a visual resume of your experience (not to mention it was policy to wear all or none and Officers usually only wear them on their dress jacket). Dwight was a 5 star and commanded US Forces in WWII, I think everyone understood his resume. Oh, and by the way, he went from a one star to a five star in 3 years (speaking of just giving things away) These posts sound like ribbon envy to me.

All joking aside, he obviously earned what he got and was humble in his display but you can scrutinize and poke fun at the guy on the right just as easily as the guy on the left depending on context and point of view.
