WikiLeaks got the information from anonymous sources, they didn't obtain the confidential documents themselves, but I understand what you mean.

It may be obvious, but your point will make more sense if you refer to what the obvious is. Just asserting that someone or something has "such an obvious agenda" means nothing when it is not actually obvious to everyone. This might be an "it's right under your nose" situation, so please point out what is in question for those of us who can't seem to see it. Don't let us stay ignorant.
