I didn't write anything for yesterday's commemoration.  Many others, most far better suited to memorializing the day, said a great deal.  My paltry mutterings would add little to what is, really, a personal day for most of us.  Like all the big anniversary events, the "where were you when" aspect makes it personal and maybe that's the most important part, I don't know. Instead it occurred to me to say something about the element of the disaster that puzzles most of us, even while most of us exhibit the very trait that disturbs us deeply in this context.  One of the most common questions asked at the time and still today is in the top 10 is: how could those men do that? Meaning, of course, how could they abandon what we consider personal conscience and common humanity to perpetrate horrible destruction at the cost of their own lives. The simple answer is also the most complex:  they were following a leader. I'm going to string together what may seem unrelated observations now to make a larger point and I will try to corral it all together by the end to bring it to that point. Firstly, with regards to the military, there are clear-cut lines of obligation set forth, the chief one being a soldier's oath to defend the constitution.  There is a code of conduct consistent with that and we have seen many instances where an officer has elected to disobey orders he or she deems illegal or immoral.  There is a tradition of assuming that not only does a soldier have a right to act upon conscience, but that there is an institutional duty to back that right up.  The purpose of making the oath one to the constitution (rather than to, say, the president or even to congress) first is to take the personal loyalty issue out of the equation. To underline this a bit more, a bit of history.  The German army prior to WWII was similarly obligated to the state.  German soldiers gave an oath to protect Germany and obey its laws.  Hitler changed that, making it an oath to him, personally, the Fuhrer.  (He left in place a rule explicitly obligating the German soldier to disobey illegal or immoral orders.) Unfortunately, human nature is not so geared that people find it particularly easy to dedicate themselves to an abstract without there also being a person representing it.  (We see this often in small ways, especially politically, when someone who has been advocating what is on its own a good idea suddenly comes under a cloud of suspicion.  Not only do people remove their support of that person but the idea is tainted as well.  People have difficulty separating out the idea from the person.  The reverse is less common, that a bad idea taints a popular leader.)  Dedicating yourself to supporting the constitution sounds simple in a civics class, but in real life people tend to follow people.  (Consider the case of Ollie North, whose dedication to Reagan trumped his legal responsibility to uphold the constitution and its legally binding requirement that he obey congress.)
