In Germany there is the notion of "Leitkultur" (eng. analogous: defining culture) which was introduced by the German conservative party (CDU). McCain, the republican president candidate is a great exemplification of this notion. Hence he believes to know what is the best way the world has to go and this way have to be the republican way of evolvement. McCain is also a do-gooder because he wants to spread the American way of life, culture and democracy all around the world. In fact he believes this is the only true way of doing things right. Furthermore he believes that Iran, an autonomic country with an old culture and many educated citizens which have elected their president democratically and clearly, have no right to possess nuclear weapons.
