This seems isolationist. Why would we want to isolate ourselves? For a country that was founded upon immigrants, that extremely benefited (and continues to) from diversity of thought and ideas, why would we want to stop that? I'm just under 30 and I still remember growing up how I was told that a major part of what made America great was the melting pot. In academia and at labs I've seen this be a huge benefit. But I don't really hear how great the melting pot is anymore (I can only think of a few times in the last decade). Maybe it was just childhood naivety. But it also seems to me that it isn't just the US that is becoming isolationist. So I have to imagine that there's something, at least in western culture, that is changing.
