A French Nazi hunter announced on Sunday the discovery of the original document establishing WWII restrictions for Jews showing that Vichy leader Philippe Petain made stringent measures even harsher.”The discovery of this plan is fundamental. This document establishes Petain’s decisive role in drawing up this position in the most aggressive way, revealing (Petain’s) deep anti-Semitism,” Serge Klarsfeld told AFP.Petain, a military hero in World War I, became head of the state based at Vichy in central France which collaborated with the German Nazi occupiers following defeat in World War II.The pencilled-in changes to the document, from October 1940, are a “profound alteration” of the document’s nature, Klarsfeld said.
