Sadly, this is all too often true. As citizens of reputedly free, civilized nations, though, we would hope those atrocities were aberrations committed by bad individuals rather than policies implemented by our leaders. Unfortunately this is not always the case. I think it's important that such policies be brought out into the light, for all the world to see what has happened. Hopefully, intelligent people in our governments will understand that having something happen to Julian Assange would only reflect badly upon those governments at this point. They would do far better to tighten up their security leaks than to worry about vengeance.
As for putting soldiers at risk, while always a concern, we have to remember that it's those leaders who started these wars who are putting them at risk, while taking little or no risk themselves. And since the war in Iraq has been declared to be over, I wonder just what risk there could be? (Yes, I know it's not REALLY over. Only in the minds of politicians trying to soothe angry voters.) I believe it is the reputation of the politicians and government drones which is endangered by these leaks, much more than the welfare of the soldiers. If the release of these documents somehow manages to get our troops recalled from those sinkholes in the deserts, I wonder how many of them would be grateful.
As an aside, these leaks, and others, point out the absurdity of thinking that our government can actually keep secrets. Those who still cling to the absurd notion that the US Government, among others, has information regarding 9/11, UFO's, the Kennedy Assassination and other conspiracies, should see just how ridiculous it is to believe that such information could be kept secret!
