Even reports that the US shot down and captured a wayward Iranian drone, flying over Shia territory in Iraq, are old news to anyone who reads "tabloid" news magazines like Wired.com. Oddly enough, specific details of Iran's overt involvement in Iraq might be one of the more startling revelations in the Iraq War Logs. If anything, the Wikileaks report might reflect more poorly on Iran than on the US.
(Admit it, this guy was right on that issue)
Meanwhile, though Julian Assange boasts that he can make governments crumble, it appears that his mental state might be crumbling instead, according the New York Times.
Update: It seems Iran's cross-border hijinks might be even worse than I thought. The NYT reports that, according to the US Army's initial Sit-rep, the three American hikers captured by Iran in 2009 were actually in Iraqi territory. (Though keep in mind that initial reports are very often wrong)
