I just watched this video; thought it was interesting. I saw a video by Wendover Productions about a year ago (the above video is not by Wendover Productions) that basically explained that one of the major successes to America becoming a superpower was our isolation factor; in other words, Geography. Because while the rest of the world was busy rebuilding after two world wars, we were able to keep our infrastructure intact and continue to build. Just imagine how powerful Europe would be today had it not been for two World Wars and numerous other isolated skirmishes. Just an observation, not necessarily related to the subject of the video, specifically. Discuss.
