In his book "Der Krieg, der viele Väter hatte", Schultze-Rhonhof argues that Adolf Hitler had not wanted to risk war right up to September 1939. In effect, he lays the blame for the outbreak of World War II substantially with Poland, citing its rejection of German offers to negotiate over the Danzig question and the Polish corridor. In addition, he notes that Great Britain, France, the United States and the Soviet Union all played a part in causing the outbreak of war given their role in encouraging Polish intransigence in the face of German requests, most especially through Britain's "" of Polish security in the event of war.
