The Jihadi appeal of Anwar Awlaqi (or Awlaki in US media)

I read an article about attempts to ban his videos on Youtube.  So I checked some of them out.  This is the reason why he appeals to militants in the West and East: he is the only Jihadi religious kook that I know who is effective in propaganda equally in two languages.  There is not one Muslim cleric or kook that I know who can propagandize in Arabic and in a Western language. Not one.  Thus, Awlaqi knows how to deliver the message to Arab youth and to youth in Western countries.  It seems that his influence grew after his death; his was far less famous before his assassination.
