WikiLeaks is a site that publishes so-called classified information that has been leaked to it. By its very nature, we cannot establish the accuracy of such a site, because we (as mere mortals in this political game) do not have access to the original classified information, or the supporting documentation behind it. In point of fact, leaking of classified information has been going on for years, sometimes for good, sometimes for bad - and, interestingly, not all leaked information is accurate - it is sometimes deliberate misdirection - and we are left with no viable way to authenticate it either way.
In the final analysis, leaking of classified information is treason, and is potentially punishable by execution.
