It doesn't work because most people talking about other countries provide next to no background reference. Nobody else knows their politicians or most of their national issues and so forth because it is not WORLD news.
Everyone, on the other hand, knows at least a handful of things -- and usually a tremendous lot more -- about the United States because the U.S. is the most powerful and influential nation on Earth -- at least it is despite our leftists doing everything they can to turn us into a 2nd world nation -- and so the frame of reference is already in place.
