  ........................ Thanks for response Shmayo   I know he fighting for USA , he raised the assyrian flag because he is assyrian, and also he raised USA flag because he fighting for them, but absolutely his nationality is determined by the place of birth of parents ( even his self born in iran (assyrian/iranian), btw, search in google about persian people ... iran is the modern name of persia, persian people and iranian ppl are the same, it doesn't matter call an iranian, persian or iranian.
