I think it's easy to overestimate America's influence on other cultures when you're looking from the outside...I remember my first week in London, I was walking down the street and saw something like three KFC knockoffs on a single block. Had a definite WTF moment there, but over time I got the impression that people were well aware of America's influences (and those of consumer culture in general) and were not terribly concerned that it was going to destroy their way of life or something. Sure there's people who are like "We'll be overrun!" when anything seen as being in competition with something traditional gains any popularity, but there's always whiners like that in every country and somehow life goes on.
The only area I can think of where America exerts a truly dominant influence on the world is in music. For whatever reason (probably because it's awesome), America's original blend of African and European elements hit some sort of enormous global jackpot, to the point where really every type of music that has become huge over the past half century+ has been in some way derived from that lineage. It's not that there aren't traditionalist holdouts (various classical and folk musics, etc), but the American sound has been the wellspring for so long that it really permeates the fabric of what people think of as music. And Chuck Berry is still alive!
