Query: Roth takes another step into post-modernism

Roth plays with post modern concepts in such novels as Operation Shylock, blurring the line between fiction and reality, between character and identity, and in The Plot Against America, he takes yet another post modern bugaboo, and runs with it. This time it is the alternate history, where he re-imagines a facist American in the late 30's and early 40's. Roth seems intent on recapitulating much of 20th century literature. His Zukerman novel's are Marlowesque frame tales, very in keeping with High Literary Modernism, while his books in the late 90's and early 00's dip into the grab bag of post modern tricks. But Roth's strength as a writer (his genius) make these moves seems less shallow then lesser writers. He takes a well worn literary clichés and makes them his own.
