Insular thinking

It all makes sense now. The reason why the average American knows so little about the world. I've been watching a lot of news on ABC and FOX and it's suddenly occurred to me that they have absolutely no world news section! Oh there's a sports section and a weather section and a finance section but no world news. Everything is US oriented and in fact pretty much all of the news that I've seen has to do with the mid-west ie just that middle portion of the US where Chicago is situated. What is up with that?
