The truth, apparently, is in there. Here's what Julian Assange had to say in a web chat with Guardian readers today
have there ever been documents forwarded to you which deal with the topic of UFOs or extraterrestrials?
Many weirdos email us about UFOs or how they discovered that they were the anti-christ whilst talking with their ex-wife at a garden party over a pot-plant. However, as yet they have not satisfied two of our publishing rules.
1) that the documents not be self-authored;
2) that they be original.
However, it is worth noting that in yet-to-be-published parts of the cablegate archive there are indeed references to UFOs.
Can't wait to see the scene-setter on our arsenic-eating Saturnian friends. I'm guessing by now they've inked a lucrative oil contract with Gazprom and don't trust Hamid Karzai either.
