See, I figure we are more of a trenched in, "nobody's going to get to us" sort of civilization. Our war machines are not terribly mobile, since their main purpose is to defend our mountain fortresses (well, that and the annual "Giant Snowball Hurling Contest"), not mobilize to invade other regions. Basically, we are really good at defending ourselves, but not so good at engaging in a ground war against outlaws (who aren't much of a threat to us to begin with) halfway across the world.
