Here is a list of detainees in Gitmo. Look down the names. Anything jump out at you? Anything at all?
True, there is one name among the 500-plus that's as western as "Julian Assange'. David Hicks was detained there for a bit over five years before being deported to Australia. But he maintained his name was Mohammed Dawood, and he was captured in Afghanistan during the US invasion, so still not quite like Assange.
