But in many ways honor and integrity means standing up for something you are passionate about. I don't feel honor is bestowed upon people for taking an oath but to hold true to that oath at all times - they all have to earn it.
Not talking to Manning or knowing how his mind works, I don't know his motivations but I do know that some of the things that have been secret or deemed sealed for a national interest have zero to do with actual protection of the country.
There are a lot of examples, from Rev King's FBI files (which are not of a national interest) to intel and information about the first world war. In the case of manning, I don't find him at fault for much of what I did in the past mainly because I took an objective look at the system and found serious flaws with it, which concern me more than the actual release of the information.
BUT the question should be on everyone's mind - does the system we have right now, this second actually conducive to protecting us or does it have more to do with protecting those who hold power that we are afraid to take away and return back to the people?

Military classification and civil classification have different standards.
