The Wikileaks situation is a double edged sword. On one hand, exposing any countries secret intelligence to the world is more than just offensive. It is downright treason to anyone involved as US citizens. And if it's not, it should be.
On the other hand, it helps the public of the US and the world become more conscious of the actions of their "leaders" and help to bring about much needed change. Essentially, the way the world has been operating for quite some time now can not work in the long term. Something had to give and this may be the spark that ignites it.
I don't know if it's true but I heard the majority of the recent leaks came from a soldier who simply put a flash drive in a computer and took all the info without any scrutiny. The real change will be when the majority of the public wakes up out of their trance and realizes the government is beyond dysfunctional and demands change.
