Guerre des Juifs
In a meeting held at the Hotel Knickerbocker on March 21 by the Jewish War Veterans of the United States of America, former congressman William W. Cohen advocated a strict boycott of German goods, stating that "Any Jew buying one penny's worth of merchandise made in Germany is a traitor to his people." The Jewish War Veterans also planned a protest march in Manhattan from Cooper Square to New York City Hall, in which 20,000 would participate, including Jewish veterans in uniform, with no banners or placards allowed other than American and Jewish flags.
