US Typography

What is US typography? Can type be described as American or English or Australian? I'm not entirely sold on the idea that typography can describe nationality. At least, not when it comes to the English language, and not without using stereotypes. Perhaps I'm simply too new to the study of typography to grasp this, in which case I would love to receive some comments on this and perhaps some links which could point me in the right direction. Following is an image from Raid71 who has done some really interesting work.

Without listing specific words, you can imagine how inflammatory using a knife in place of an "I" could be. It works here as it is relevant to the movie. As an exercise in graphic design, I really like this work. I'm not sure of the font, but perhaps it is appropriately 'bold', 'strong', 'concise'... Of course the more words I use here, the harder it becomes to avoid the political overtones of describing "America". Perhaps this is why I have a problem with trying to define a US type. It is too subjective.
