Christopher Caldwell: What is Europe's problem with Islam?

Youtube description: Europe has received a wave of immigration from the global south in recent decades, similar in scope to the US—but very different in its results. Many immigrant and second-generation communities have astronomical unemployment rates and a thin connection to European identity. Some have produced terrorists. The problems are particularly severe among newcomers from the Muslim world. Why has Europe had so much difficulty assimilating its immigrants, and why has the U.S. had it easy, even with high rates of immigration from Mexico and Central America? Is it Islam, European prejudice, or both? Christopher Caldwell, who writes for the Financial Times, The New York Times Magazine and The Weekly Standard, visited Zócalo to talk about themes from his upcoming book, Reflections on the Revolution in Europe: Immigration, Islam and the West.
