Nationalism in the Twentieth Century

Do you know this book: Anthony D. Smith. Nationalism in the Twentieth Century. New York: New York University. Press, 1979? I heard he support synthesis of marxism and nationalism.

I'm not really familiar with Smith's work. I read that he is a sociologist who specializes in nationalism, but I really don't know whether or not he incorporates traditional Marxian class analysis into his research. I haven't found any evidence suggesting that he is a Marxist, so I doubt he advocates any such synthesis. I could be wrong, though.
