I recently read an interesting thing about this in a collection of e-mails, stories, and letters from the war on terror in "Operation Homecoming." One was an e-mail from a soldier who said he met an American citizen originally from Iraq now living in Dearborn, Mich., who was visiting Iraq and told him that eight of his friends, also from Dearborn, had died in the service of the new Iraqi Army. Apparently, they'd left Dearborn to join the new Iraqi Army. Not the US military, though.
