I just don't really care how anybody feels about their job or the decisions they made, it's really out of my control. That goes for the army guy, the Wall Street stockbroker or the art major... which doesn't mean I don't have my own opinion about some of those decisions, but really, everybody largely makes their own bed, then lie on it, and then we deal with it or not. The "dragged on the street" argument is really relative (extraordinary rendition comes to mind). I would just say that, largely, we've understood that dissent and criticism are integral parts of a healthy society. The question is what to do with those societies that didn't get the memo. Bombing the living out of their cities and killing their families in the name of their own freedom sometimes sends the wrong signal, IMO.
Now, notice that none of the above really involve service members decision-making, that's why I don't pin any of that on them.
