USA versus Europe

Some people, like Christopher Caldwell, believe that Mexican and Hispanic immigration to the United States is not something to be worried about, despite some short-term problems with assimilation. On the other hand, Caldwell is more concerned about large-scale immigration to Western European countries from Islamic countries. Caldwell’s book Reflections on the Revolution in Europe: Immigration, Islam, and the West, goes into this in more detail.
