I do not think there is one root cause we can narrow the current world views on the United States too. It is a combination of many, many things. I think it stems from Hollywood's portrail (sp?) of us via the movies exported, our own image we export of ourselfs when we travel, the media, and what seems to be a Conservative/Republican/Right-Wing dominance in this country (I can't spell today) while the world seems to be falling more to the Liberial/Democrat/Left-Wing. I think a lot of our (as a country's) actions and failed actions and the doctrin of be re-active vice pro-active in military efforts etc......
