That's not completely true. Take for example the most recent diplomatic leaks. While they have provided a fascinating look into the world of international politics, some of the info they posted was down right dangerous. For instance, Iran now knows that its neighbors wants the U.S. to attack. What is that going to do to the already dangerous situation there? On the same token, North Korea has been told that China, their biggest ally, would consider abandoning it. Assange really should not have leaked some of these documents. We don't need to know everything, and we shouldn't know some things.
