From the WaPo, by Anne Applebaum an article 'The connection between Boston and Europe’s train bombers', which ends with:
“I do not have a single American friend,” Tamerlan Tsarnaev reportedly said of himself. That’s the kind of statement that might have been made by a young Pakistani living in Coventry, or a young Algerian living in Paris.

We don’t expect to hear it from someone who grew up in Boston, a city that has taught generations of foreigners to become Americans in a country that likes to think of itself as a melting pot. But now it might be time to change our expectations. These terrorists are a lot less like the 9/11 attackers — or the Columbine attackers — and a lot more like the men known as the Tube bombers of London or the train bombers of Spain. Our response is going to have to be different — very different — as well.
