The spotlight's fallen on the hidden side of the US "War on Terror" this week after the magazine Vanity Fair published an interview with a highly controversial figure - Erik Prince, the founder of the private security firm, Blackwater. The article claims that Blackwater assembled a team that followed and made preparations to assassinate a suspected Al Qaeda associate living in Hamburg.
