National identity is not always easy to define. The artist Wassily Kandinsky, for instance, was born in Russia, lived in Germany, and died in France.

Taken to Israel as a young boy, the pianist‑conductor has spent his adult years living in London, Paris and Berlin. An Israeli by choice, who has been granted honorary Palestinian citizenship, he will support Argentina at the World Cup. "I have multiple identities," he told me some years ago in Chicago (another of his homes), "but my football loyalty will never change."
