     The Plot Against America is a novel by Philip Roth published in 2004. Instead of reconstructing real

historical events, Philip Roth offers something bolder: a reconstruction of imagined events, a "what if...?"

that reads like a "what really happened".

     Just suppose...that the air hero Charles Lindbergh, the man who made the first solo transatlantic flight

in 1927, who earned huge sympathy when his baby son was kidnapped and murdered five years later,

who called Hitler "a great man", just suppose that he'd run for president in November 1940, and took

advantage of the feelings that undoubtedly existed then (No more war! Never again will young Americans die on foreign soil!), and that instead of Roosevelt being elected for a third term and taking America into

Europe to fight the Nazis, Lindbergh won a landslide victory. And then he signed non-aggression treaties

with Germany and Japan, and introduced a set of anti-semitic(反犹太人的) measures which were a

betrayal of the rights and liberties in the constitution(宪法) and yet they were accepted by the mass of

ordinary citizens and even by some Jews.

     The narrator is Philip Roth, aged seven, and the family at the book's centre are his family-father

Herman, mother Bess and brother Sandy. The Roths understand the threat posed by Lindbergh, but

each member of the family responds differently. Early on, there's a trip to see the sights of Washington,

where the Roths find their pre-booked hotel room has become mysteriously unavailable. An obvious

case of anti-semitism, Herman shouts, and a violation of the principle that "All men are created equal".

But his loudmouth protests embarrass Bess. Already there's a pressure to pretend not to see what's

going on. Further disagreements arise when Sandy disappears for the summer for an "apprenticeship"(学徒期) with a Kentucky tobacco farmer. Worse, after he successfully encourages other Jewish city boys

to follow his example, he's invited to a reception at the White House through his aunt, Bess's sister

Evelyn. While Herman refuses Sandy permission to attend, Evelyn defends Lindbergh as a freely elected

democrat.
