Postmodernism and The Yiddish Policemen's Union

Postmodernism deals with irony and playfulness in looking at The Yiddish Policeman's Union the whole novel is postmodern. The novel is postmodern because it takes place in an alternate Alaska. The novel states that the Jews reside in Alaska because in 1948 when it was propose to make Alaska a refuge for the Jews the one individual who would have oppose it had been hit and kill by a cab. That fact in itself makes the novel ironic.
Another thing that makes this novel supremely ironic is that Berko's mother died indirectly because of something Berko's dad Hertz Shemets did. "The prayer house at St. Cyril," Berko says."The riots." "The St. Cyril riots," Hertz Shemets agrees. "God damn it." "Berko--" "God damn it! Indians always said it was the Jews that blew it up." "You have to understand the pressure we were under," Hertz says."At the time." "Oh, I do," Berko says."Believe me. The balancing act. The fine line." "Those Jews, those fanatics, the people moving into the disputed areas. They were endangering the status of the entire District. Comfirming the Americans' worst fears about what we would do if they gave us Permanent Status." "Uh-huh," Berko says."Yeah. Okay. And what about Mom? Was she endangering the District, too?"
I can think of a Disney show that is postmodern the same way that this novel is Phil of the future. The story is base around the fact that a couple opened a time capsule which made them nostalgic about the past so they rented a time machine and traveled back in time. While traveling back it time the family ran into some time machine trouble causing them to be trapped in the past. While trapped in the past the family added thing to the time capsule that the couple original open which made them nostalgic.
