- Wikileaks itself has not so far broken any laws. Although laws may have been broken by individuals who leaked the information, Wikileaks has exposed secrets to all, including those who were keeping the secret. This is journalism, not warfare.
- Embarrassing those in power is all leaks have ever done. Attacks against leaks have always centered around an anti-nation or anti-those-in-power bias. Wikileaks and its activities are nothing new or unique.
- A leak does not have to contain incriminating information. Ostensibly, the point of leaking information that's subversive, criminal, or immoral is to prevent it or seek justice from who have committed these acts. Those who are glad that Deep Throat leaked information about Nixon or Daniel Ellis leaked information about the Vietnam War would say those were justified and important leaks. However, in legal and journalistic terms, its difficult to define a justified or unjustified leak.
Some have come to the organization's defense:
called Wikileaks director a terrorist (Mike Huckabee) and flip-flopped on his status as good or evil (Sarah Palin).
Note that one of the diplomatic leaks has been about Monsanto's dangerous products, so the issue more than just about embarrassment. However, the point still stands.
