In an audio tape in which he blames the West for climate change Bin Laden "praises the political analysis of Noam Chomsky."
"Noam Chomsky [the US academic and political commentator] was correct when he compared the US policies to those of the Mafia. They are the true terrorists and therefore we should refrain from dealing in the US dollar and should try to get rid of this currency as early as possible.

Noticed from google that this isn't the first time he's done it, in the past calling him one of the most capable of Americans. Weird.
Not weird at all. Bin Laden is simply trying to get in on that "antimperialist" thing that is so popular with leftist mentals everywhere.
