Considering that I've done combat deployments, I'm seeing the ramifications invoved with the leaks in a way that's going over your head. Reading your posts, it'd probably take a paradigm shift for you to see the ramifications of releasing secret military related videos out in the open, where our enemies could grab themselves more material to take out of context, and to turn into massive propaganda films.Of course Robert Gates, Secretary of Defense, and others in the military (I think at least one of the joint chiefs of staff) have been quoted that they cannot point to any incident of harm to the troops from any of the Wikileak releases. They could of course be lying but I'm really not sure that they would have the incentive to do so if the idea is to put pressure on Wikileaks.
I agree that we (although you addressed WTF) are coming at this from such vastly different starting points that agreement on these issues is unlikely).
In terms of propaganda there is plenty out there that isn't classified that could be use. But along those lines: Should the abuses at Abu Ghraib have been kept under wraps by the media because they would provide propaganda? Should the media have not reported that the US used waterboarding because it would provide propaganda?
