Usually that sort of thing is because somebody got the wrong headed idea that the American military existed to "do the right thing." In the sense that the current idea of American exceptionalism comes from the same place, perhaps. Again I really think that it's a different thing. Manifest Destiny was about growing the nation more than it was about military involvement. There's a connection, but I don't think it's quite the sameAnd as for Manifest Destiny, isn't that the justification for our intervention in the Balkan conflicts in the 1990's? For intervening in Somalia? For intervening in Lybia? For intervening in other people's conflicts anywhere? For the nation building that we do? An exercise in futility? Usually. Justifiable? That's what this debate is about.
